I'm not surprised, I don't think it has anything to do with AI, it's the same in blockchain and prob in all other fields.

I think ppl underestimate the cost of context switch between languages, even if you're really proficient in more than one.

If you're a team with 1-2 eng and have to build a frontend, you are forced to use js/ts. Now, if you can keep everything in a monorepo in the same language, you're simply moving faster. And I'm sure people will criticize and bring counter examples... but statistically 60-70% of the teams will just be faster working this way.

My first startup was frontend php, backend python, 2 eng; soon we specialized one working on frontend, the other on backend, it's tedious to context switch. My last startup was typescript for everything, again 2 eng, same code base, same coding style, both iterating on all code. (And daily I work in rust & C, I'm definitely not a frontend eng nor a js/ts enthusiast, I'm just reflecting on efficiency.)
