I don't know you are being downvoted. There are already instructions in ARM chips to help with JS floating-point conversion [1]. Yes, while the "Java chips" never got into the mass market[2], JS and it's ecosystem is eatting the world in a way Java never did and the trajectory is only increaing.

P.S. I know WASM isn't JS, but I'd still consider it in the JS ecosystem.
