50 years is insane for software. There may be 1 or 2 versions of 1976 software that people still buy today, although I’m skeptical. 30 years is also far too long; same deal for 1996 versions of software. Who’s buying new copies of Windows 95 today? 20 years seems about right.
Continuing down that line, Windows Vista turns 20 in a few weeks, and is equally irrelevant. IIRC even the default Windows 7 installer has issues with AHCI, so your SATA SSD won't even work correctly out of the box, much less NVMe. And then of course there will be no video or networking drivers for modern hardware.
10 years seems closer to obsolescence, and that's for productivity software.
