### *Example Input Text:*

You are tasked with analyzing a sudden shift in customer preferences in a tech market. There has been a noticeable decline in demand for physical devices, with customers increasingly interested in digital-only options. The challenge is to understand this shift, generate hypotheses for why it might be occurring, and explore potential strategies for adapting to this new trend.

---

### *Processed Output with System 1 and System 2 Thinking:*

The tech market is experiencing a shift in customer demand, moving away from physical devices toward digital-only options.

[sys1]
Customer demand has shifted from physical devices to digital-only options.
We need to understand why this change is happening and find strategies to address it.
Key factors may include cost, convenience, and technological trends.
[end sys1]

[sys2]
**2.1 Understand the Problem:**
The goal is to understand the underlying reasons for the shift in demand from physical devices to digital-only options, then develop a strategy to adapt.

*Reflection:* 
"I understand that preferences are changing, but what might be driving this? Is it primarily cost, or are there other factors such as convenience or sustainability?"

*Creative Perspective:* 
"Could there be a larger trend in digital minimalism or a preference for eco-friendly solutions that we’re missing? What unseen motivations might explain this shift?"

**2.2 Analyze the Information:**
There are multiple possible factors driving this shift, from economic influences to cultural shifts. It’s essential to isolate each factor and understand its impact.

*Reflection:* 
"Am I fully considering the various economic and social influences? Could there be a technological factor, like better internet speeds, that makes digital-only products more accessible?"

*Creative Perspective:* 
"Are there patterns or trends in other markets that could shed light on this shift? Could this be part of a larger trend toward virtual experiences?"

**2.3 Generate Hypotheses:**
1. Customers prefer digital options due to lower costs. (Confidence: 0.8, Creative: 0.4)
2. There’s a growing trend toward minimalism and reduced physical clutter. (Confidence: 0.7, Creative: 0.7)
3. Digital products offer greater flexibility and ease of use. (Confidence: 0.6, Creative: 0.6)
4. Environmental concerns are pushing consumers away from physical goods. (Confidence: 0.6, Creative: 0.8)
5. Advances in tech make digital-only options more functional. (Confidence: 0.8, Creative: 0.5)
6. Pandemic-era remote work increased demand for digital solutions. (Confidence: 0.7, Creative: 0.6)
7. Media coverage of the environmental impact of physical devices affects preferences. (Confidence: 0.5, Creative: 0.7)
8. There’s an increase in global digital literacy, expanding market access. (Confidence: 0.6, Creative: 0.6)
9. Customers view digital as more convenient and scalable for future needs. (Confidence: 0.7, Creative: 0.5)
10. Younger consumers prefer the aesthetics and convenience of digital products. (Confidence: 0.6, Creative: 0.6)

*Reflection:* 
"Have I considered all possible influences? Are there any surprising factors that could explain this shift?"

*Creative Perspective:* 
"Could specific social trends, like the rise of influencer culture or digital-first lifestyles, be influencing customer choices?"

**2.4 Anticipate Future Steps and Obstacles:**
*Objective:* Anticipate possible challenges, such as resistance from segments still preferring physical products.

*Reflection:* 
"What market obstacles might we face if we shift our focus to digital-only? Are there sub-segments that still prioritize physical products?"

*Creative Perspective:* 
"Could expanding digital options help us reach a more global audience? Are there emerging trends that we could leverage in our strategy?"

[end sys2]

[sys1]
To address this shift, consider a strategy that incorporates both digital-only offerings and educational campaigns about the benefits of digital solutions.
Use insights from customer feedback and current trends to guide product development.
Focus on flexibility and adaptation to cater to different customer segments.

Q:

Ubuntu 18.04 strange behaviour of date with --date option

I've found strange behaviour of date program in Ubuntu 18.04.
So, I consider date should work with --date option and correctly process +N minutes:
date --date "2019-01-01 13:43:32 +1 minutes" "+%Y-%m-%d %H:%M:%S"

But, in Ubuntu 16.04 I will get:
2019-01-01 13:44:32

And in 18.04:
2019-01-01 12:44:32

The solution is add +1 hours as well, but, wait a minute, why I'm getting minus one hour when I do plus one minute?

A:

The problem here is that date is treating the +1 part as the timezone, and not as an extra minute. The extra minute is coming only from the word minutes which is parsed as "add one minute" because it is unclear.
You can see this if you try the following commands:

Your original command, which is interpreted as if it says "at time zone UTC +1".
$ date --date "2019-01-01 13:43:32 +1 minutes" "+%Y-%m-%d %H:%M:%S"
2019-01-01 12:44:32

Change to +2 and notice that the hour is reduced by one but the minute stays the same. This is interpreted as "at time zone UTC +2".
$ date --date "2019-01-01 13:43:32 +2 minutes" "+%Y-%m-%d %H:%M:%S"
2019-01-01 11:44:32

Observe that just using +1 (without minutes) gives the behavior of only changing the hour, not the minute.
$ date --date "2019-01-01 13:43:32 +1" "+%Y-%m-%d %H:%M:%S"
2019-01-01 12:43:32

Observe that the word minutes is interpreted as adding a single minute.
$ date --date "2019-01-01 13:43:32 minutes" "+%Y-%m-%d %H:%M:%S"
2019-01-01 13:44:32

Here is some of the relevant documentation:

From the info date command output, section 21.1.6 Options for ‘date’:

... For example, ‘--date="2004-02-27 14:19:13.489392193 +0530"’
specifies the instant of time that is 489,392,193 nanoseconds after
February 27, 2004 at 2:19:13 PM in a time zone that is 5 hours and
30 minutes east of UTC. ...

Note the use of +530 to describe the time zone.
From the info date command output, section 28.7 Relative items in date strings:

... The unit of time may be preceded by a multiplier, given as an
optionally signed number.  Unsigned numbers are taken as positively
signed.  No number at all implies 1 for a multiplier.  Following a
relative item by the string ‘ago’ is equivalent to preceding the unit by
a multiplier with value -1. ...

Note the text: "No number at all implies 1 for a multiplier".

So how can you get around this?
One option is to reverse the order of the string elements:
$ date --date "+1 minutes 2019-01-01 13:43:32" "+%Y-%m-%d %H:%M:%S"
2019-01-01 13:44:32

Another option (the option I'd prefer) is to explicitly specify the time zone:
$ date --date "2019-01-01 13:43:32 UTC +1 minutes" "+%Y-%m-%d %H:%M:%S"
2019-01-01 13:44:32

(Note that you can also use +0 or Z as alternatives to UTC in the string above.)

Also note that if you are using date version 8.26 or newer (as Ubuntu 18.04 is; 16.04 is using 8.25), you can add the --debug flag for date to tell you how it parsed the input text:
$ date --date "2019-01-01 13:43:32 +1 minutes" --debug "+%Y-%m-%d %H:%M:%S"
date: parsed date part: (Y-M-D) 2019-01-01
date: parsed time part: 13:43:32 UTC+01
date: parsed relative part: +1 minutes
date: input timezone: parsed date/time string (+01)
date: using specified time as starting value: '13:43:32'
date: starting date/time: '(Y-M-D) 2019-01-01 13:43:32 TZ=+01'
date: '(Y-M-D) 2019-01-01 13:43:32 TZ=+01' = 1546346612 epoch-seconds
date: after time adjustment (+0 hours, +1 minutes, +0 seconds, +0 ns),
date:     new time = 1546346672 epoch-seconds
date: timezone: system default
date: final: 1546346672.000000000 (epoch-seconds)
date: final: (Y-M-D) 2019-01-01 12:44:32 (UTC)
date: final: (Y-M-D) 2019-01-01 12:44:32 (UTC+00)
2019-01-01 12:44:32

vs.
$ date --date "+1 minutes 2019-01-01 13:43:32" --debug "+%Y-%m-%d %H:%M:%S"
date: parsed relative part: +1 minutes
date: parsed date part: (Y-M-D) 2019-01-01
date: parsed time part: 13:43:32
date: input timezone: system default
date: using specified time as starting value: '13:43:32'
date: starting date/time: '(Y-M-D) 2019-01-01 13:43:32'
date: '(Y-M-D) 2019-01-01 13:43:32' = 1546350212 epoch-seconds
date: after time adjustment (+0 hours, +1 minutes, +0 seconds, +0 ns),
date:     new time = 1546350272 epoch-seconds
date: timezone: system default
date: final: 1546350272.000000000 (epoch-seconds)
date: final: (Y-M-D) 2019-01-01 13:44:32 (UTC)
date: final: (Y-M-D) 2019-01-01 13:44:32 (UTC+00)
2019-01-01 13:44:32

Final note: I have no idea why you get a different output on 16.04. On my 16.04 machines I get the same result as my 18.04 machines. I also looked through the git history of GNU coreutils, and I don't see any commits that would have obviously caused such a change.
