We have missed "celebrating" a milestone during the pandemic.

Cool! We can all sing it Happy Birthday. For real now that the song
has been declared out of copyright and now in the public domain. :-)

It's an odd kernel though. And I think that hurt GNU by choosing to
go that direction. Because it just never got moving.

If you are not part of the problem then there is good money to be made
supporting it long term!
AIX was a basis for a lot of embedded products such as Netapp NAS
boxes. I think they now have products based on GNU/Linux too. But I
am pretty sure the big iron Netapp boxes are still using IBM AIX.
Makes me wonder how many other embedded uses exist.
My opinion using AIX was that it was a solid kernel but a less than
pleasant interactive user experience. And at the time that was as
compared to HP-UX which I had been using extensively.
AIX also came with JFS which is a reasonable alternative to SGI's XFS
file system. Probably a good combination with a large NAS server.

Downtime? What downtime? :-)

I had often heard of HURD being described as technology of the
future. Always has been and perhaps always will be.
Canonical supports some live Linux kernel updating as well. As I
recall it is a paid subscription service. But it does seem possible
to update the Linux kernel in place while running too.
