There are some good ideas in there (the main one IMO is structured objects as the main form of IPC, instead of text), but the execution is really bad after XP and maybe 7. They stuck to a lot of legacy garbage in the name of "compatibility", but in the end it's an inconsistent mess of dozens of frameworks, and yet many old programs run worse than they do in WINE on Linux. Now with the advent of vibecoding the core components, it's pretty much over unless they literally start over from an old checkout.
