The actual non-snarky first step would be to admit that we are over our depth and we can no longer deliver software that is reliable, secure and maintainable. We can only guarantee that our software works for at least some users, on current versions of OS/browser, and is hopefully secure against some of poorer attackers.

Countless variants of programming languages and of instruction sets are not an issue. The problem is lack of well-defined non-leaky interface on boundaries of abstraction layers.
