VSCode is Microsoft's product, and they are doing solid job with it now, but who knows what they will do with it in 5 years' time. I won't be surprised if they try to integrated it with Azure more closely and do some things which are not relevant to me. Plus it's Electron app which I won't use.
And it's not like open source solution can't fail and be abandoned.
Only two editors that I think will last forever (at least it seems so now) are emacs and vim. Everything else has similar chances of surviving test of time.
