I also didn't enjoy it, sloppy boundary drawing combined with some motivated reasoning. He explicitly distinguishes research from development in paragraph 4, but then spends the rest of the essay treating "fast" and "legible" as inherently inferior without consistently applying his own distinction...like, If you're building a bridge or shipping software, legibility and speed aren't signs you're not pushing boundaries...they're signs you're being competent. also, he seems to suggest that slow thinking is actually a different kind of intelligence that institutions miss. But this conflates processing speed with intellectual ambition, plenty of fast thinkers work on hard, illegible problems.... Plenty of slow thinkers work on trivial ones.
