Just like fortran and COBOL themselves, the pre-AI / ML stuff will be around for much longer than we will be.<p>I've been having this weird feeling lately which I figure must also be what the fortran / cobol / mainframe folks felt... I guess I learned to code in the late 90's / early 2000's with perl, linux, C / C++, shell, etc... which was basically just the mainstream way to do stuff at the time, nothing terribly esoteric.<p>Nowadays, I work at BigCorp places that have a lot of systems that have probably evolved from similar times, and it's easy for me to troubleshoot / diagnose / improve them... but the younger folks in their 20s seem pretty lost with really basic shell stuff, how to grep, how to ssh / rsync / copy files around the place, how to #! + chmod +x scripts, etc. Even after a few years on the job, they're not proficient - it's weird, because the systems still exist and probably will for decades to come, but I feel like we're only a few years away from this stuff being as esoteric (but also, still relied upon) as cobol + fortran.
