This differentiates senior developers from the rest I think. Mind you, I can also understand why a lot of people - myself included - think "what's the point", given how (in my own experience), a lot of software - mainly front-end - is replaced every 5 years, and major architecture overhauls every 10.
My current employers is currently replacing their SAP-to-API middleware with some commercial point-and-click software to, drumroll please, AWS lambda functions written in Typescript. It's an improvement, because there's more transparency and performance measurement instead of things hidden behind a GUI, but it's also a risk because it's set up by consultants who will eventually move on to somewhere else.
Already there was suddenly a presentation that came across as Authoritative about how they have Chosen to use Kotlin. I don't know for sure if that was to replace typescript but... it really doesn't matter to me tbh.
