Is there any genuine speed benefit in making MAME enforce now SSE4.2? Else this does solely spin the obsolescence hamster wheel further. (Though shalt not obey Microsoft.)
Technologies tend to spoil after a certain sweet spot of development. Typically it starts with the split between pro and household grade versions of a device class, making the latter artificially shortlived and functions dumbed down.
* sewing machines (many presets but flimsy plastic cogs jam by thick cloth)
* washing machines (crack-prone plastic tank with unremoveable bearings, tiny power components self-desolder by overheat)
* music keyboards (presets-only instead of editable sounds, button beeps spoil stage use)
* TV (very fragile TFT screen, overheat, user+firmware in same flash memory, cloud dependency and spyware, OLED shortlived with "burnout compensation" always-online spy mode)
* online devices (designed to spy by unremoveable battery, no lens cover, no mic switch, no mechanical power switch, remote maintenance, SSD causes unexpected dataloss (by write loops & poor cooling, unsuited to keep old devices unpowered), no screws to deter repair, pulsed microwave radiation).
Cloud obsolescence even affects vehicles (Van Moof bicycles got unusable by company bankruptcy) and household appliances those would never need app and online connection at all.
10 years later, bad properties of the household variants tend to seep back to the pro versions, or the latter get designed to be made unusable for non-professional users (enterprise SSD with only 2 weeks unpowered data retention time, non-wifi routers need connected PC to boot before corded phone works, LAN switches hold no setup data when unpowered etc.) Nonprogress should not be furthered.
