There is better than even odds I'm older than you, so I'd recommend you rethink using phrases like "possibly longer than you've been alive", it's not ... polite regardless of people's age.
The point (and I'd encourage you to find that thread to not retread ground) is that we absolutely can compile most computation heavy code for these different targets reasonably well - what we cannot garentee is that the resulting code is optimal given context. But gosh we can do so much - I’d encourage you to look into in profile guided, target aware, and autotuning optimization etc. (and then of course, there are LLM guided optimizations, but that's a whole other kettle of fish)
