Whatever your thing will run on, will it still work in another 30 years? Our hardware is so flaky that everyone in the industry is depreciating at 3-5 years or less. Sure, platforms can stay the same, hardware-wise, but you'd be really lucky if you can still run the same software that you did before.
And yes, you can run an emulator, but who's going to maintain the underlying platform? Is it going to be connected to the internet and be part of the next gargantuan IoT DDOS attack.
What those guys is need is another Comodore 64, brand new. It has proven it works, why change it?
We need to take a serious look at this stuff: this is what we should be doing. Not writing yet another freaking web server, but stuff that can still be operational in 30 years.
