DislikedYou are correct in many ways. These days programmers are not as disciplined as they used to be. Instead of writing efficient code, we have compilers that attempt to optimise it. However, even that is not enough so the solution is not to build a Rolls Royce but something that works because cost and release time is a big factor.
Now if you want things to work faster, rather than getting code further optimised, it is far cheaper to throw hardware at it. So in your case I would recommend getting solid state drives. I personally don't have one...Ignored
There are even solutions to boot in your virtual machine as your main OS when needed (like for playing games). You can hide VMs on encypred drives etc..
