No, I vaguely remember booting the first 64 bit cpu (on real hw) for
the 2002-2003 time frame. I need to check my memories on a more exact
date, but you guys from Suse should know better. So 15 years are not
yet over and I really would like to wait at least until then. Another
question is if 64-bit simulators take into account here.

Though, I assume a discussion on this topic will at least take 1-2
years, so it's good to start with it now. Also, I really would like to
finally switch off and retire my K7 which still runs some regression
tests (will need to check the actual used kernel version). It was a
good time, but now I realize it's somehow over. Considering this and
