Their main issue IMO is that they are not really bringing anything major to the table in exchange for the very high cost of breaking compatibility with nodejs. If you are going to create a competing ecosystem it has to be somewhat revolutionary for the cost of investing/migrating to a whole new ecosystem to be worth it.
I like Typescript quite well, but if I'm told I'm going to throw away my nodejs/ts code base and start from scratch, then they are many alternative with better (for many definitions of "better") langages to consider, which at least will actually be different from what I have just thrown away.

This is why my money is on Bun, just like a safe bet in Carbon. Both are designed to be drop-in-capable in large codebases where the bean counters aren't going to budget a total rewrite that redelivers the same functionality.
