I think this is just my choice of wording, friction as a means of slowing down and thinking something through is useful. Friction isn't just a roadblock. For all the times you want to do something exotic, throw an hour or two at it and in the process realise it was a bad idea and a more elegant idea emerges. That, that's the kind of useful friction I mean.

But overall yes, time spent thinking is the thing that matters.

It's less "there should be more friction" and more "LLMs remove too much". Instant gratification is great if you're a consumer, awful if you're a creator.
