I think it makes total sense for JetBrains, and a bet on multi-vendor is something that speaks sanity to me. JetBrains has never talked VC bull**t and I'm glad they are not losing their minds for AI
(JetBrainer here.) When I give conference talks, I introduce JetBrains as: private (never taken VC), profitable, and European. We are indeed focused on being AI Realists, on the side of coders who still want to code.
