Even if OP's estimates are "WILDLY off", there still aren't many out there Multiply his estimate to 1000 per F500 company ... that's only half a million Put a pair in every major geography ... that's only 5,000,000 And, for kicks and giggles, multiply by another 10 for funzies That 50,000,000 Yes, it's "a lot" ... but it's nothing compared to commodity hardware According to a quick web search, Google alone had in excess of 1,000,000 x86 servers about a decade ago That's one (large) company I've worked with myriad companies who're running 10s or 100s of 1000s of x86 servers (let alone x86 desktops/workstations/laptops) - with nary a mainframe in sight (or maybe a couple ... which is on the order of "none" next to 100s of 1000s or millions of x86 boxes) Per Microsoft [0], there are 1.4 billion Windows 10 and 11 devices (yes, I know that's not a server count, but it speaks to the orders of magnitude difference between x86 devices and mainframes ...even with my generous estimates posted above) ----------- [0] https://news.microsoft.com/bythenumbers/en/windowsdevices https://news.microsoft.com/bythenumbers/en/windowsdevices
