My bet is one ultra-hardened, minimal, front-facing system which does N-modular redundancy which N systems, each written on a different stack/different language.

The hardened software picks the computation that wins the majority.

It's not an issue to write all the implementations in the various stacks/languages: we'll have better and better LLMs to help us.

This shall bring security and shall allow to detect shitload of bugs (both in the implementation itself but also in the stack).

Heck, this could even be compatible with GP: one of the implementation could be JIT'e by a LLM, others could be written in advance (and Lean formally verified). Not sure which sense it'd make though.

I'm 99.9% sure it's coming for if it's not, I'll make one.
