Re: The Lessons of Baltimore, 1904 have not been learned
Ubuntu and SUSE dropped 32-bit last year and Arch at the start of this year...
This is incorrect. 32-bit versions of the latest releases of all three of these distros are still available.
You may be thinking of support for older members of the x86 family lacking support for some SIMD instructions or PAE (which almost certainly also lack 64-bit support).
