(This is my understanding of the artical with some help from other comments. I probably use some words incorrectly but I think you can get the jist)

TLDR: He is't abandoning the current stance that passive > active but rather is discussing the real value of the underlying assets.

And he isn't challenging on that stance either. I don't think the artical is out right advocating people to switch their personal investments from a passive index fund to an active one since he & we both know that passive funds tend to do as well or better than active funds after accounting for fees.

However, the article (at least how I understood it) is saying total effect of everyone moving their money into ETFs and index funds means that the underlying stocks have an increasing risk of becoming or being overvalued since no one is checking the underlying stocks/companies anymore. As someone just tangentially interested in this topic I've thought of this before in a more tangable way: since every college graduate or hacker news type person knows that index funds are the best then at some point 'everyone' or enough of the population has a stake in index funds that it's likely to be overvalued.

The market should/could correct as expected: undervalued companies go unnoticed longer since everyone is passively investing causing actively managed funds to have higher yields (since they can get 'all' of the undervalued companies passive investors miss) and people adjust their holdings accordingly. However, as a few other users stated there a few issues trying to hedge against a buble:

1. Solvency - The market remains 'irrationally' attatched to passive/index funds which means that index funds continue to beat active funds anyway despite their 'real' value/gains being pure speculation. It's difficult convincing people to let you manage their money when your making 4% and the S&P400 is making 8-11% so remaining solvent is an issue.

2. Systemic Risk - Large markets & financial products are intertwined so if index funds are overvalued then it effects the economy & financial institutitions and if it crashes/pops then it sends a shock wave throughout all of them. Finding a hedge that isn't effected by a bubble in one financial product (CDOs, index funds, etc) can be tricky.
Yeah I think the consensus is that 100% passive would be terrible.

Jack Bogle's view was that if the market is 50%+ passive indexed that would be bad news.

Some folks argue that the number is even more extreme, that passive indexing generally increases efficiency, and that as long as there are even a handful of active investors, the market will still be efficient: http://www.philosophicaleconomics.com/2016/05/passive/

The same author had another thought-provoking argument that the popularity of indexing has probably driven up stock valuations: http://www.philosophicaleconomics.com/2017/04/diversificatio...

Except humans crash into stationary vehicles in lane all the damn time. Most highway pile ups are a simple crash lots of folks drive into the back of. Why's it hard?

A vehicle coming from a side road has a lot of movement within your field of vision. When driving on a highway we're well used to the fact and expectation that stuff isn't stopped. When the vehicle ahead emergency brakes or stops you have the growth of size of the target to gauge by. That's not much movement, until the last moment when it's far too late to evade. Some stationary debris is much easier - it's not meant to be there at all - you transition to evasion right from the get go.

For a human in a car, the dangerous highway case is the stationary vehicle in the fast lane, maybe one or two vehicles ahead. When flying it's the other aircraft that's on a collision course. Neither will move within your field of vision. Neither is easy to detect as problem, until it's very late.

FWIW 4 year old humans often run into things. :)
In a/c you have plenty of things to do to keep you occupied.

The autopilot disengages itself with a loud warning (and leaves aircraft in a reasonable attitude and trimmed).

Pilots are indoctrinated into disabling automation at the very first sign of something going wrong with it.

Autopilot operation is significantly simpler and understandable by the user (i.e. you may have "roll mode" keeping wings level, "heading mode" and "nav mode" which keeps wings level and either keeps nose pointing to commanded heading or following the pre-programmed track, "altitude hold" or "vertical speed (with or without altitude intercept)" for vertical control, etc, etc.

Aviation autopilots do simple commanded things. They don't make decisions on their own. They are much closer to cruise control than to Tesla's "autopilot". And, yes, a typical aviation autopilot will happily fly you into a mountain if you're not paying attention (the official term for that is CFIT, controlled flight into terrain).

The aviation industry is trying to improve safety by adding more warning systems and situational awareness aids (such as TAWS and ADS-B). Systems which "protect" the a/c by making and automatically executing decisions for a pilot are widely regarded with suspicion (and for a good reason, too: MCAS issue with 737 MAX is just one example of a "safety" system killing people).

Expectations can be challenging, but a great deal of a leader's job is effectively communicating any gaps between expected performance and actual performance.

In my experience, more often than not, "tough love" becomes conflated with toxicity, which causes people to start avoiding crucial conversations in order to avoid the perceived toxicity. Important feedback can become stifled by our desire to maintain a congenial and friendly atmosphere. We forget that some of the toughest times come when we're suddenly blindsided by a situation that's been brewing for months or years, that we were blissfully unaware of. Our first indication of a problem is being passed over for a promotion, or not receiving a return letter.

This is an unfair situation for all involved parties. Honest feedback during the internship may have given the author a chance to adjust course, instead of being (justifiably) dismayed by a surprise result. By allowing this communication failure to occur, and not granting the courtesy of clear feedback, the leader in question damaged a relationship with a talented engineer, someone who may end up working for a competitor, or even starting a competing startup.

You can't build a business if you need 10-15 half baked assumptions/bets all to be true for it to succeed. Robotics startups need to internalize an attitude that consumer robotics will never be a thing. Of course they will, but the comparative ease of targeting industrial applications makes consumer robotics such a challenging path forward for a startup to take.
I suspect the purpose is to put something in a cable that a commercial manufacturer would never put in a cable. That way, he can look at it and be reminded that "I made that", or he can brag about it when someone else sees it and asks.

I've watched people fly RC airplane and helicopters with gas engines. They still exist, and there are air fields for them. I've seen them since the 90s as a kid. They aren't expensive but, are bigger and require an actual landing and takeoff area.

I didn't know the but rate, but I learned this studying in computational linguistics. Languages that seem "fast" tend to have more phonemes per semantic unit than "slow" languages. In general, languages with a lower lexicon of phonemes require more of them to make a "word", they get spoken faster. So the semantic units per period of time remains fairly constant across languages.

I think the lowest hanging fruit in robotic household automation right now is folding laundry. An interface like, put your clothes in the in-basket and this device folds them. I could imagine a world where instead of washer and dryer, a nicely equipped house will have a washer, dryer, and folder. This is especially useful once you have kids.

Anyway, email me if you’d be interested in building this :P
How about before robots doing chores maybe a whole house volume (TV's, Doorbell, Phones, Microwave) level control to keep kids asleep. There is a lot of simple improvements that could go a long way toward making everyday life better that could happen before domestic robots.

Tools like autopilot encourage lack of attention.

The problem isn't "you don't have pay attention to X" it is "you don't have to pay attention to anything during normal operation". It is human nature, if not outright physiology that it is incredibly difficult to keep someone engaged, and paying attention to a task that they are not actually doing.

The problem with halfway solutions like autopilot isn't that they control the car some of the time, it's that they can, essentially without warning Stop controlling it.

Self driving cars will happen. But the current model is essentially "do enough of the driving to maximize the likelihood that the human 'driver' is not going to pay attention, but don't do enough to make their lack of attention safe".

My statement isn't "cars allow you not to pay attention", it is "systems like autopilot actively encourage a lack of attention", that's backed up by the need for alert systems when they have obvious signs that the driver isn't paying attention, like "no longer holding the wheel". If the system didn't in general usage result in lack of attention then such a system would not be necessary.

Yeah, but it's an important point that taking risks without a model can lead to solutions that would not be found otherwise. Suppose there are ten options for survival and 100 people who are under threat. If they try to develop a theory and all fail, and do not act without hope of success, then they all die. If they develop a theory and follow it, and it is wrong, then they all die. But if at least one option is correct, and they simply try them at random, disagreeing with each other, then about ten people will survive and pass on their genes and/or knowledge.

People are not 100% rational, and being 100% rational is not evolutionarily optimal.
Yes and no, it seems its an external module. And this is part of the problem - why would I need an external dsl extension to translate a pure relational concept into SQL?

Thats the whole point of the autocalibration process. The autocalibration process figures out how the IMU & video sources are aligned.

Would you say the same about the JVM, JavaScript (SpiderMonkey + V8), RVM, cPython, and other bytecode VMs? I don't see how a bytecode VM leaves performance and compatibility on the table.

IMO LEGO thrives thanks to their relentless focus on product quality. The phrase "det bedste ir ikke for godt" (roughly "only the best is good enough") has a long history in the company. The fact that they have been able to thrive like this in a market with many competitors cloning their product is a a testament to their product quality and related brand strength.

If you've used and compared the various brands in this space, you'll be familiar with the quality variations. LEGO has put immense engineering effort into having the best plastic and tightest tolerances in the industry, and I can really feel the difference when building.

Here's one example comparing some of the clone brands to LEGO's own products:

https://uploads.brickset.com/docs/clonebrands_v1.7.pdf

Other brands do continue to improve, and there are many companies out there that make very nice building toys, but LEGO has done a nice job making sure that everything they ship is of good quality.

>But, he says, instead of being limited by how quickly we can process information by listening, we’re likely limited by how quickly we can gather our thoughts. That’s because, he says, the average person can listen to audio recordings sped up to about 120%—and still have no problems with comprehension.

The deduction that is quoted does not follow: speeding up audio recordings with 120% results pressing both the auditory system as the language and thought systems (or any other potential bottleneck) to be sped up proportionally since it's a pipeline.

Similarily the posted article (I have yet to read the original one) states in the title that "human speech" has a universal transmission rate, but the research tested reading not speech, so this may or may not be true.

Perhaps the bottleneck is human speech, with the side effect that listening is never trained beyond the typical speech rate limit. (in this case the higher speed syllable languages would be easier to pronounce fast, and the lower speed ones harder to pronounce fast)

Perhaps the bottleneck was in the visual burden of reading, a language that encodes more bits per syllable implies more types of syllables, which irrespective of size or number of characters puts a classification demand on the visual system (classifying a symbol coming from a set of only 2 symbols will be easier, but will require more classification instances than classifying from a large set of characters but with fewer classification instances).

Perhaps the bottleneck was again in speech during reading by subconscious vocalizing of the text.

Perhaps the bottleneck was in the auditory "speech to syllable" classification.

Perhaps the bottleneck was in parsing text.

Perhaps the bottleneck was in "accessing thoughts" etc.

So it is rather hard to identify where the bottleneck is located without having a means of detecting where in the brain the "incoming queue is full" vs "incoming queue is waiting" during speaking, listening, reading. And which of these 3 causes this universal bottleneck (since I gave 2 examples of how an apparent bottleneck in reading could stem from not being trained beyond a possible universal bottleneck in speaking rate...)
Anecdotal, but the FPV drone pilots I've seen are much more responsible and aware than photography drone pilots (I'm a part of both communities).

Photography drone pilots will do all kinds of stupid shit that horrifies me, like fly near people, near obstacles, under trees, in crowded places, etc etc.

I blame it on the fact that a Mavic is super easy to get and requires no knowledge, whereas it took me two hours of reading just to figure out how to start my racing drone.
At this point I'm just waiting for some of these tech companies to drop their analytics and drop targeted advertising, and just ask users for their advertising preferences or do advertising the traditional way... why do we HAVE to have targeted advertising?

> esp. in spontaneous spoken language, then the information rate should be about the same.

This is entirely non-intuitive to me. I would think with language evolving that some would be faster than others. If language starts as conveying extremely simple thoughts then it should take longer to convey certain things. I would then assume that as the language develops it gets better at conveying ideas. I would think that thoughts could go much faster than how we process it with language. Like I have constant thoughts that are really fast and can be complex. There's no internal dialogue there. But when I think with an internal dialogue it is much slower.
