What about the effects of 'time spent on the problem' (ie compounding)? If you are only learning for learning sake, then getting to a "101" or "102" or "103" (to use American college level terminology)is fine I would assume. This might take 1-3 years of learning/study/doing.
But if you truly want to "master" something - then does "constantly thinking about problems" mean you will never benefit from the same 'compounding' effect as someone who has spent 3/5/10 years of their time on that problem?
Or - is all your "need for cognition" - mostly in one domain space (e.g. "Computer Science" or "database structure" etc)?
Also see previous recent discussion of indoor/vertical farming (2017) - (1) and (2).
As discussed on that thread, vertical/indoor farming is great for leafy greens (mainly water but but not much other nutrients or carbon), but much harder for other plants.
See this video [3] - "Why Vertical Farming Won't Save the Planet: Bruce Bugbee, Utah State University Department of Plants, Soils and Climate, has studied plant growth in controlled environments for most of his career. Here he presents the results of his analysis of the environmental effects of Vertical Farming/Indoor Agriculture (September 2015)".
A copy of the slides can be downloaded here (the link shown on the youtube page is dead - correct link[4]).
CBW Bank - founded by an-Ex google engineer and an ex-Wall Streeter has been doing this (created a bank from bottom
Up - including purchasing an actual bank and creating the software) geared towards startups) since 2014. Don’t know how well they are doing now.
But they wouldn’t have had the in-built In go-to-market strategy, or the prestige/visibility in the funding community, of a YC Alum.
Not being harsh to the OSSU team - they've done a great job and hopefully they can comment on this - but I prefer TeachYourSelfCS. - Because (a) they provide both Book AND Video/MOOC resource for each topic and (b) its a lot more apparent what the 'core' knowledge you need to attain to get a solid undergrad level knowledge base is.
