I'm retired after 44 years in IT. I haven't seen it all, but I've seen enough to know, just like everything else, IT repeats itself, and keeps re-inventing the wheel. Me, too.

Having started in the "Goodle Days" when 512K of real memory with 250MB removable disk packs was a monster machine; a lot of coding was still done in Assembler and COBOL; one tested on the production machine during the day, and ran batch at night, I've noticed a few minor changes in the industry. No big deal.
