I'm also pretty cynical of most JS rebuild/reinvention projects. I'm very tentatively excited by this one _because_ it looks like all it does is incrementally improve. Having something that is a drop-in API compat replacement for yarn 1/npm and node makes it potentially really easy to get the benefits of incremental perf improvements _without_ needing to reinvent the wheel like yarn 2 or deno.
100% this. Being compatible with nodejs API makes it possibly useful, unlike some other projects which want to throw away the huge npm ecosystem. Why on earth would anyone use JS (or even TS) server side if not to benefit from the ecosystem? Unlike on the web, there are plenty of better languages to use if you don't want npm.
For me and possibly other full stack devs, because I don't want to stay current in two different languages. Using python and JavaScript sucked. Switching to Node and JS was much better.
