I think you are missing the point. The larger the scale is, the more things may be optimized and the more you need to be careful to focus on the important "3%". That said, it doesn't hurt to analyse in advance which parts might be critical and steer the architecture based on those observations.
It's still moderately bad. Raspberry pi is limited to 2 gen3 pcie lanes which is ~4-8x slower than the drive (and you will likely be further limited by cpu speed)
If the engineering demand is lower than the engineering supply, you're still winning. If your transactions per second only amounts to 60% of the Pi's capacity for a given use case, why complain?
I agree with this. My hobbies tend to completely take over my thoughts and then it is difficult to switch to work context. It's much simpler for me if my hobby overlaps with my day job. If I get better in my hobby, that helps at job and vice versa.
This is so much out of touch with reality. You somehow assume OP is interested only in profitable projects and that idea validation is easy. It's not. For technical person it is much easier to code a prototype/mvp than to try to get potential paying customers by any other fake landing page means. 1000 customers? You are dreaming.
While your use case is valid, it's nowhere near as annoying to have to wait 1 second for a button to enable than it is to call random person from your contacts because his name appeared under your fat finger. Maybe there can be a distinction between expected layout change and ad-hoc elements appearing, like notifications, list updates etc. I would probably go too far asking for a setting of "time to enable after layout change"
I think a mindset to "get rich" or even worse "get rich quickly" is reallt bad for everyone even outside tech. There is certain amount of wealth you need so you need not to worry about food, shelter, kids, education, health, etc, that's all right, but beyond that it's just getting destructive. When do you feel "rich enough" already? $1M? $100M? If you don't worry about getting rich and just be ok with being mid-class, you can code whatever you like. Even without getting single dime from the hobby code you will learn a lot, you will get good with tools and quick to find solutions, easier to be employed and progress in your career. And I would believe happier in the long run.
