I hear you, but I have subtle disagreements:

> Why not read books, manuals, or take online classes? There is free access to all these things, the only cost is time and energy.

Sure, but it's just way faster now. I can get the exact right piece of knowledge I need to advance my understanding on demand, rather than having to spend minutes or hours tracking down the right information, then scanning around the text to filter out all the irrelevant stuff.

There's also a motivational effect: the activation energy of bothering to do this was such that in many domains, it didn't seem worth it.

> Everyone has tons of ideas

Most people have profoundly bad ideas

> Those nuances and details don't go away. They don't matter any less. They only become less visible. But those things falling apart is also incredibly valuable. What doesn't break is the new foundation to begin again.

Agree, however that's the challenge of this time. Things are becoming less visible. On the other hand, you can implement and get that feedback ten times faster, or point ten minds at stress-testing a concept in 3 minutes. For many of my projects, that's the difference between getting anything done vs idly fantasizing. For others, it could easily be irrelevant.

> The bottleneck has never been a shortage of ideas nor the hands to implement them. The bottleneck has always been complexity. As the world advances do does the complexity needed to improve it.

I don't think this is a coherent statement. How could you possibly surmount complexity with anything other than better ideas and more hands?
