Until that console processor fails with no backups. I seem to recall
having 4 or 5 "backups" (aka operators). ;)

Obviously it is simplest if somebody (or machine) outside, loads
the code into memory, and then triggers a GOTO.

But, if adequately appreciated, you are probably no longer the cheapest.
So, they tried to replace you with a machine.
