I think the Anthropic acquisition means that Bun isn't in that business anymore. Bun is still fixing fundamental Node problems, but that's no longer the business.
The business value the Bun team needed to deliver (to make the acquisition pay out) might very well be this controversial, but nevertheless spectacular, 6-day Zig→Rust port.
But beyond that, now Bun is just tooling used internally at Anthropic, which also happens to be open-source.
Oh. Well, then, yes I agree. It certainly does remain to be proven if anybody can make "Node, but better" a business.
Certainly the recent layoffs¹ of ~half-or-so of the Deno team doesn't bode well for it, as AFAIK Bun was the only other significant player trying (to make it a business).
