Eh, this sounds like the people that have been replaced at a lot of companies already.

>"the website has a certificate that needs yearly renewal"

For example, why modern certificates are being dropped down to very short times. The push to automate everything.

>"unpaid bills are handled this way"

Any company that has things like this will start changing their process.

You have this idea (and maybe the AI company CEOs do too) that this will be like a container drop in. No, instead these things will be part of a gradual process change and human parts will eventually disappear.

>So that alone I think guarantees a good amount of unreplaced jobs.

What percent. This is what matters at the end of the day. Once unemployment reaches high rates over all age groups in a society that is used to low unemployment things go bad. It can take longer to go bad where you have social safety nets and jobs programs, but in places like the US that is communism, so expect the haves to shoot at the have nots.
