This might be more pedantic RE the comparison to Google, but there's a good subset of people who think that Bitcoin provides no value.

I think there's a lot of interesting innovations in the space, but I can think of a lot of counterarguments to Bitcoin's "value". These are points I've heard...

- distributed ledger:
In practice, things that require ledgers also have a degree of trust between parties. They also usually are bound by contracts and laws. Enforcement power is necessary for ledgers to be useful

- store of value:
Many different securities exist with less volatility. Also I either store my value in exchanges I can't trust to stay solvent, or I am now hiding my BTC under my figurative couch and can't use it super easily.

- Transaction mechanism:
For small transactions, the mining fees are prohibitive and the speed's not great. For large transactions, banks work fine. Each transaction uses absurd amounts of energy

I think the blockchain is interesting (smart contracts as a thin layer under "real" contracts), and can come up with theoretical use cases. But large-scale "real" usage needs to happen for a lot of these counter-arguments to become less compelling.
This feels like slide ware to me, and I know Tesla has achieved its goals in the past, but color me at least a little skeptical.
I wonder at what speed you get that range. Those specs are in Bugatti Veyron league, even beating it at acceleration (for 1/8 the price tag), but at full speed, the Veyron empties its full tank in... 12 minutes. I'll let you calculate how many miles that is at 250mph.
I'm a Tesla skeptic for model 3 success, but this is badass.

If I was in the market for a car that I couldn't take advantage of driving legally, and had 200k laying around, would definitely buy lol

That's profoundly disappointing, I agree, but in a sense perhaps we geeks only have ourselves to blame. We didn't solve the basic (to any normal user) problems of ease of use and security, despite having decades to do so. We also didn't start routinely educating the next generation of kids in how useful and powerful programming skills are. Consequently, for many people personal computing has been reduced to little more than a mechanism for consuming online content and for relatively simple communications using a few trusted channels.

The one comfort is that someone still needs to be creating all that content and all those communications channels, and those people are always going to benefit from something much more capable than a small, lock-down touchscreen+WiFi device.
Toyota owns Lexus, Ford had Jaguar and Land Rover, Hyundai owns Genesis, Volkswagon has Bentley, Fiat owns Ferrari. Just like other car manufacturers, Tesla does it all.

edit: Ford didn't start Jaguar.
Pretty mich every car company makes a high end sports car. This isn’t a pivot, this is establishing Tesla as a car company with a range of cars rather than just 1 or 2 that are very similar. Product diversification is a good thing for companies that make physical products. The manufacturing process and higher margins on this will likely fund new developments that will trickle down to the less expensive models.
Would ludicrous mode for the roadster go 0-60 in 1 second?

the 620 mile range is super impressive. How??? Or is it just that the roadster is super light?
Yes, that's what I meant by coverage of the relevant branches. But the good news is that all these partial, heuristic sources of information can be combined. E.g. for detecting function entry points, you can combine information from ELF/PE export tables (if present), function prologues detected by a linear scan, vtables, static CALL targets, dynamic CALL targets from run-time traces, etc.
Bold prediction: if they manage to produce a battery capable of 620 mile range promised, it will essentially be game over for ICE cars. My bet is that next generation of Model S and X will easily be in the 400-500 mile rsnge.
I seem to recall reading that the Veyron's tyres will disintegrate after 15 minutes at top speed, but that's OK because it only carries fuel for 12 minutes.
It's supposedly "in progress", but there is no end in sight: https://en.wikipedia.org/wiki/Metrication_in_the_United_Stat...
Wheel torque is not the same thing as engine torque. I'm pretty sure the confusion is intentional, since it's the first time I see wheel torque advertised for any car.
In case you are not aware, British people on HN are way outnumbered by commentators from the US, so HN is US centric and by no way UK centric.

Also concerning the nation-centric point of view, people from the UK are way less focused on their country and know other people outside their country exist.

If you are from the UK, take my apologies.

If your from the US, case in point.
That's the thing. Blockchain tech is still pretty early stage in terms of reaching the general consumer. Yes, Bitcoin has been around for 8+ years now, but it takes a damn long time for a brand new type of technology to mature and work out the kinks. Ethereum has only been around for about 3 (2014).

It's easy to look at the space right now and see that it isn't currently viable, but that sentiment completely ignores the passage of time and the fact that we are moving towards the goal of general applicability.

Yes, there will probably be a 2000's style shakeout of all the failed or mislead or me-too attempts, but the fact that there are so many projects popping up should tell you that we are still trying to figure out what we can and should do with blockchain.
200mph top speed is just a consequence of the base abilities of the car, it does not really matter in practice, but the fact that the car is capable of doing it shows that it is really powerful and very aerodynamic. Besides far away niche uses like tunnels under LA and autonomy, in Germany you could drive 200mph if you find a good stretch in the early morning ;)
0-60 in 1.9s for $200k that is affordable by a good range of people. I can see disasters happening with this car as young dudes lose control when they accelerate.

There has to be some serious A.I to prevent this.
> No exotic carmaker will be able to match it.

Did you fact check that? Actually, Bugatti is pretty close and partially outperforms, although at a way higher price point. https://en.wikipedia.org/wiki/Bugatti_Chiron

0-60 mph in 1.9 sec

This might sound really stupid. But isn't performing such acceleration on a daily basis close to the limit of harming one's health? I mean micro concussions for example.

Really curious because that acceleration is amazing!
0-100kph in 1.9 seconds is the sort of performance the Group-A Jet Sprint boat I used to copilot had. That's with a 600+ hp, methanol powered drag engine. At full power, it could pull a full G accelerating.

That performance in a road car would be mental. However, you can still manage it quite well - there are supercars (and highly modified street cars) that can pull similar numbers, and you don't immediately die when driving them so long as you have the experience. Having breath lockouts and such is almost offensive to the sort of people who can handle these sorts of vehicles.

I'd be more inclined to suggest a buyer preselection system, or at least offer in-house driver training.
So a charging station will need what, 10 hectares of land for the solar? Either that or 10 kW of grid interactive solar for marketing purposes, while absorbing the bulk of the electricity from the grid.
> it's worth pointing out that the urban areas in the South are pretty damn progressive

The urban areas everywhere tend to be pretty progressive. The political and cultural distinctions between any given state's urban and rural areas are a lot more profound than the distinctions to be made based on West Coast, East Coast, South, or Midwest.
When the battery can be refilled in minutes, it will be game over. Until then...
Also I wonder how many times you can accelerate like that... maybe only once with full charge?
> Also why no RWD version?

Two words: Snap Oversteer

The thing would have so much power and torque - with the drivetrain weight over the rear wheels - that a RWD variant would probably be scary.
I absolutely agree with number two. I love coding and solving problems but I get so much more enjoyment if it's something I believe in too. I'm fortunate to be at a place where I can actually listen to the non-techs and say "what you're doing is so cool, what tools do you want me to make?".

The Tesla Model S P100D has the exact same 0-60 and 60-0 times. So Tesla has already achieved that, but with a much heavier car.

It depends on your metric for success. VR already has research applications and artists are using it for 3D modeling. VR gaming is neat, but in my expectations, not going to be the core focus of the technology.

Generally, VR is about natural control of a simulated environment. I suspect within a few years, when our hardware gets better/is stable and more groups are developing applications, you'll see VR become a central component of more systems.

That may change, of course.

Apple needs to buy Tesla and run it better than Elon Musk can right now. He's overloaded himself with responsibilities.

Apple could do a lot of good by applying their skills to such an important problem. And Tesla's have been called "laptops on wheels" which has some truth it. They have the money, people, and management skill to do it well. Tesla has the industry lead that Apple needs to get in the race.

First thing Tim Cook would do is cancel the semi project, I'd guess. But maybe not.
This car is smaller than a Model 3, though, and the 3 can only fit <80kwh.
My brother pointed out that other Tesla cars (even the semi they announced) have a "front trunk". This one's hood is seamless. Our theory is that under the entire front hood is batteries.

Tesla doesn't run a volume production line. All the major players have production lines that make about one car a minute. Tesla isn't able to play in the big leagues until they can do that.
Too bad it can’t maintain that performance for any extended period of time. Battery is known to overheat if you drive it too hard.
Performing a short is a sort of counter to to-the-moon talk. If you look at the mechanistic properties and costs associated with shorting, you can see how far the person buying the short thinks the value is from open market value. If you were to bet against the sun rising tomorrow, the market would "bet" to the contrary and the short would be cheap and accessible.

It's not craps gambling, it's like betting on a boxing match. The bookie odds are based on previous records and some valuation model, you only come out ahead in the long if you have a superior valuation model, insider knowledge, luck, etc.

Optical computing. I remember talking to a bloke working on it back in 1990, and he said they had a working optical transistor so all the hard bits were done. Soon we'd have computers that used multiple frequencies of light to process operations concurrently on the same hardware!

Musk stated in the presentation that they plan to use solar with on-site battery storage at these "Mega-Charger" stations and will guarantee a max electricity cost $0.07/kWh. No grid needed (my phrase, not his). Not sure if it is doable, but that is the plan.

I wonder what the handling will be like. Teslas on the track have had over heating issues, and cornering performance has been just average at best.

Not every exotic car owner (Ferrari, Lambo, Mclaren) brings their car to the track, but I feel like a good % do. When you own a 200k car, you don't drive it to the grocery store because it attracts too much attention, and you worry something bad will happen to it.

Edit: For more clarification on the grocery getter comment: As an owner of an older exotic car, I've seen that most do not drive their exotics that much. 1-5k miles max/year. The cheapest insurance policies won't let you drive it to any public parking lots. And policies from the normal companies will cost $3-8k in large metropolitan areas for 40-50 year olds. So where do you go? You make excuses to drive it. Cruise to a friends house, drive in the mountains, or to the track if you have time. Daily errands are for your other car. Why risk it. Elon's a pretty good showman, and he makes me feel like I could do anything with this car! But, alas, 200k, I want it to be perfect forever. Even used in 5 years @ 130-150k.
Musk did note those are (supposedly) the base specs of course. So the higher cost versions may surpass the Bugatti accordingly.
As a Tesla Model S owner, you really don't need to fill your car in minutes. It's a totally different (but not bad) mindset.

Every morning my car is full, because I plug it in in my garage. So if I don't go more than 260 miles that day, it's plugged in the next night. It doesn't matter that it takes a few hours. My gas car was just sitting in the garage each night anyway doing nothing. How many hours does your car sit idle per day? Probably way more than enough to charge it for your daily driving.

For road trips, there are super chargers.

I was a bit worried, after hearing all the fuss about range anxiety and all that. Overall, charging has just been such a non issue.
I read elsewhere it has 6800 18650 li ion cells. I haven't fact-checked that yet, mind you.
Generally wheel torque would be quoted in the gear that gives you a 1:1 (or close to) ratio. Hence in a lot of cars a dyno run will be done in 4th gear as higher gears are generally overdrive gears. Also your calc is missing the final drive ratio.
I always wondered why engine torque was put on the spec sheet. Since geering can turn that engine torque into any number you want at the wheels. Wheel torque seems much more relevant.
This concept is about 100% cold shower, whereas the article is about 1min of cold at the end of a hot shower. Do you think there is a difference on effectiveness? I would think the extreme of hot-to-cold would be more affective, and after 60 seconds, your bodys already adapted.
Not to mention that once the benchmark is set, everyone competes to break it.

See: Hennessy Supercars
I'd say Elon is doing just fine. The semi business long term could be a game changer that propels Tesla beyond a car company. Think fleets, partnerships with FedEX, UPS, DHL, long haul companies, van lines moving companies, Amazon deliveries. Lot's of very lucrative business opportunities. Also, the pickup truck market in the United States is huge, Tesla is getting into that as well.
For those of you in SF, you should look into Noisebridge. They don't have nearly as many tools or machines as TechShop, but they have a lot and it's all free.

Yes. The Chiron matches it in speed, but not acceleration. 1.9s vs 2.4s to 60mph.
Since the roadster has a 250+ mph figure, the tires are probably going to be one of the limiting factors. (same with the Chiron).

"
The Chiron can accelerate from 0–97 km/h (60 mph) in 2.4 seconds according to the manufacturer,[4] 0–200 km/h (120 mph) in 6.5 seconds and 0–300 km/h (190 mph) in 13.6 seconds. In a world-record-setting test, Chiron reached 400 km/h (250 mph) in 32.6 seconds, after which it needed 9.4 seconds to brake to standstill.[14]

The Chiron's top speed is electronically limited to 420 km/h (261 mph) for safety reasons.[2] The anticipated full top speed of the Bugatti Chiron is believed to be around 463 km/h (288 mph)."
Matching the price is part of what "match it" means.
Huh, that’s pretty interesting. I guess if it’s smooth enough, doesn’t even need to spend all night cruising, can just get you to a campsite an hour out of town.

You haven't just deflated the plan behind this entire, multi-year undertaking with your 5-minute analysis, as if you know more than all the engineers working at Tesla. The tone you're taking is just ridiculous.
I used to navigate/copilot a 480ci methanol powered jet sprint boat, Group-A class. It would pull just over a G accelerating, and did the 0-100kph sprint in 1.9 seconds.
That boat could also do 100kph-to stop-to 180 degree turn - to 100kph the opposite direction in about three seconds. (This is something unique to jetsprint boats, they can pirouette like nothing I've ever experienced). That pulled insane G's, so much so that you needed the HANS device around your neck to stop the weight of your helmet breaking your neck.

Imagine having to strap into a HANS device to drive a road car. I want this future.

The price of bitcoin may be bubbly but the tech isn't. Most of the people buying in to bitcoin and crypto right now are chasing $ and are mostly driven by speculation instead of an understanding of the tech behind it and its potential.

Warren buffet wrote a good piece about the expected value of buying ownership of a chunk of the us economy (i.e. shares) vs. buying gold.

The former is normally a good investment, because it grows. Gold just sits there. It’s decent as a store of value compared to cash, but that’s about it.

Google is a company. It had a high valuation because some people expected it to grow larger and earn future revenues.

Bitcoin seems more like gold. What does it do? Why should it have more value tomorrow than today?

The only reason I can come up with is that it has intrinsic scarcity, like gold, and can be a store of value. But this doesn’t seem very convincing - other people could make other blockchain based currencies.

Can someone explain why bitcoin ought to be worth more money in te future?

Sure, having more features gives a model more opportunities to overfit. But having more data points has the opposite effect, since they reflect the underlying distribution better and therefore provide a better estimate of actual model performance.
