Does Medicine also work?

I don't know about the medicine. I have not been in any medicine related project, so far.

Regarding the banks, they can't use AI. This is a big security risk for them. They need to keep really, really high level of confidentiality. They need to cover all kind of audits: internal, government, external, etc. No audit will pass, if any of the documentation and implementation go to the cloud.

Highly regulated!

I guess, if the medicine follows the same high level of confidentiality, AI won't be used there as well.

No AI, no push to use it -> normal expectations of time and effort ;)
