Might be something like "IBM? What's that?"

Red Hat Enterprise Linux

That is the certificate I earned upon completing community college. Their Linux curriculum was originally designed around Debian, but when IBM acquired RHEL, redesigned to offer this foot-in-the-door.

IBM still seems to do alright in the legacy mainframe/mini market. It is quite strange how the AS/400 and zOS stuff all goes without notice of ordinary IT guys like me, as if it didn't exist, but still powers a lot of machine rooms that aren't AI data centers.

"I guess we'll need to learn how to program those quantum computers in the end"...

"I haven't heard of that LLM model, how is it?"
