Like you pointed out, the current stack is heavily unoptimized and has a terrible architecture; it's only the way it is because of happenstance and tides of the market (companies always reaching for faster over better). An actual "nirvana" in computing like the other guy said would require bulldozing a good chunk of our current stack, keeping only kernels and core utilities, if even.
I really wish we had a bigger focus on getting good foundation instead of making yet another JS framework and SaaS, but then again, who's paying developers to actually do something of quality nowadays?
