I'm not nearly as detail-oriented but I can certainly relate. The craft I've spent 20+ years mastering is disappearing and I'm not sure if I'll enjoy whatever replaces it. It's reassuring to know there are others who share the sorrow.

It's such a strange feeling. I have a similar amount of time invested as you. I'd always gravitated toward understanding how things work and bringing those insights back to whatever I worked on. Could be low level details, could be software architecture, or some obscure SQL. It wasn't that I knew everything, but that I could descend into the rabbit hole and re-emerge with something useful if needed.

Hard not to see it as tech killing competence in general, and cheering it on.

Kinda wish I'd gone to med school instead. Tech has only shown itself to be more unserious as time has gone on.

Software isn't disappearing - Code is. The craft is more craft than ever and more powerful.

Your job will probably disappear, if it involves creating software.
