I think more about the timing being incorrect - betting on software in an era of exponential hardware growth was unwise (software performance can’t scale that way). The problem is that you need to marry it with a significantly better CPU/architecture because the JIT is about not losing performance while retaining back compat.
However, if you add it onto a better CPU it’s a fine technique to bet on - case in point Apple’s move away from Intel onto homegrown CPUs.
