There was an OOXML compatibility layer for Office 2000, though the latest version of that only runs on Win XP and later, but I suspect LibreOffice would be more compatible with OOXML made with current versions of Office.
The governments, yes, but not the general population necessarily. And the governments can't survive without oil revenue and/or external support, so they'll be losing in the long run.
Nah, if anything the Islamist groups are biding their time, waiting for the internationally-supported governments to lose the will to carry on before striking.
I was thinking, in a world without DRAM, cobalt-infused magnetic tape (like that used for VHS and ferricobalt cassettes) or metal particle tape, digital sound recording would still be possible using 1960s black-and-white VTRs that took ferric oxide tape not dissimilar to those used for analog multitrack recording.
Their hardware business was doomed by 1998, FF7 and Gran Turismo had given PlayStation momentum that neither Sega or Nintendo could hope to match, but Sega was in a particularly tough spot because of years of misguided decisions.
They could have extended the Saturn's lifespan to 2000 and thrown their lot in with the PS2 after release, but it seems many people at SoJ were emotionally attached to the idea of selling consoles.
The S4 Mini ended up being a legendary long-termer as its drivers were built for the 3.10 kernel, which was still being patched by Red Hat two years ago.
Win8.1 x64 required double-width compare and exchange instruction support, so people who bought Win8 for a CPU or motherboard that didn't support it had to downgrade to the 32-bit version or lose support in 2016.
Win7 updates from 2018 onwards required SSE2 with no warning.
Win11 24H2 and later won't install on x86 processors that don't support the x86-64-v2 baseline.
KDE lost some corporate support when SUSE changed their default to GNOME in about 2005(?). I think it sees some use in the automotive world but aside from that it's all volunteer work.
