This is a long term pattern in the JS ecosystem, same thing happened with Yarn.

It was better than npm with useful features, but then npm just added all of those features after a few years and now nobody uses it.

You can spend hours every few years migrating to the latest and greatest, or you can just stick with npm/node and you will get the same benefits eventually

I have been using pnpm as my daily driver for several years, and am still waiting for npm to add a symlink option. (Bun does support symlinks).

In the interim, I am very glad we haven't waited.

Also, we switched to Postgres early, when my friends were telling me that eventually MySQL will catch up. Which in many ways, they did, but I still appreciate that we moved.

I can think of other choices we made - we try to assess the options and choose the best tool for the job, even if it is young.

Sometimes it pays off in spades. Sometimes it causes double the work and five times the headache.

If Node becomes much better thanks to the existence of Bun, then I think Bun accomplished its goals. Same for C and Zig.
