How far are we from the days that banks are fully operated by AI Agents?

Just a few years ago, RBC, the largest bank in Canada, had me print out a web form and mail it into them to open an account.

We are a long way from the point where a bank will trust an AI agent. They are still working on trusting online forms.

We really don't need a unique "Ask HN: When will AI replace" for every product, service and profession out there.

"fully operated" meaning that the average customer can't get human service? Or meaning that there are no humans - so the AI is the one signing off on the bank's financial statements, meeting with government regulators, and negotiating with the Board's Compensation Committee?
