In some narrow sense, this headline reminds me of this Alex Murrell blog post from 2023 called "The Age of Average": https://www.alexmurrell.co.uk/articles/the-age-of-average (HN discussion from that time: https://news.ycombinator.com/item?id=35355703). Covers the strange phenomenon of cultural homogenization, with all designs (cars, buildings, brand logos, websites, etc) reverting to a mean. In some sense, I'm not surprised now that AI (or 'thought' more generally) is doing the same.

Sort of, but not quite. There's some actionable takeaways here IF you're not betting on an intelligence explosion / software singularity. If that happens, everything in this blog post goes out the window. Notwithstanding that in the next, say, 20-30 years, there's some practical advice in here.
