I have to be honest I do believe Node.js will be around for a long time. The improvements over the past few years have been vast thanks to the ever improving standards and all the major cloud companies are heavily invested. It has the world's largest public package registry as well (not that the sheer quantity means you can always find a high quality library).
I've only recently switched after years of scepticism but for the sort of stuff I do it's more than good enough. It has its warts but so does every language that's stuck around.
I don't necessarily think that the the language or the core thing won't stick around. But unless you force people to really decide which packages they require, you end up with an unaudited mess of packages (basically with every package - or is anyone really creating portable, stable apps of a relevant size based on the core node environment ...)
