Never underestimate the longevity of systems, since new systems tend to be built on top of old systems.

Though I do not know any, I'm pretty sure in 2021 there *are* mission/security-critical applications running on 6502s in a number of places in the world.

The 6502 is one of the few processors validated for embedded medical devices. From https://www.westerndesigncenter.com/ ".. the 65xx microprocessors protect millions of lives annually within embedded heart defibrillation and pacing systems. " Can't get more mission-critical than that I suppose..

This makes me happy. One day some of us could end up with a 6502 keeping us alive, and perhaps writing 6502 code.

Sometimes the world makes me grin.
