> Companies can do more with internal development/retraining and institutional knowledge is a thing especially with large organizations
I remember, many years ago, being tasked with teaching PHP to the mainframe COBOL team - we’d retired the mainframe, and all our COBOL apps with it, but we’d kept the team, and management had struggled with finding them something else to do. It was a painful experience, they were getting it, but very slowly. Didn’t help that I wasn’t the best teacher, I had to slow myself down a lot and found that a struggle - but I was young and inclined to say “Yes” to everything.
Eventually, they were all laid-off - and pretty much straight-away found new COBOL jobs (with a higher salary too). I think, in the end, they were happier that way.
