When John Fowler left, it was all over. So long as Fowler was with Sun
and then with Oracle there was a chance that big sparc machines were
still going to be shipped. I own a few. Sadly that business is all but
dead and you can not even run the latest Solaris on a sparc server at
all unless you want to buy their top of the line million dollar
machines. Everything else was dropped off a cliff.

It would be very cool to get Debian linux running on a M-4000 beast with
256G of memory but the fences to climb over are very high and then there
are mine fields to crawl into.

It is far far more fun to just go to RISC-V and do good stuff there.

So very true and so very sad. I was a big fan of the OpenSolaris
project which at least gave us ZFS and some other items. However
that CDDL license disaster is just a mess. A minefield mess.
