For one I do not want to run my startup at the mercy of VC funded tech. Node.js is open source and maintained by a foundation, it will not "run out of funds" or be abandoned if there is no profitability in the near future.
Yeah, but it's not a big bet. Deno can do it, Bun can do it, if they die a tragic VC-fueled death then somebody else (maybe Node) can do it. Using Bun to me is just like using a microwave oven in 1980 — there weren't a lot of microwavable convenience foods yet, but you could sure heat up some leftovers more conveniently and quickly.
