Have you used Amazon Q? It's actually pretty handy at investigating, diagnosing, and providing solutions for AWS issues. For some reason none of our teams use it, and waste their time googling or opening tickets for me to answer. I go to Q and ask it, it provides the answer, I send it back to the user. I don't think an "SRE Agent" will be useful because it's too generic, but "Agent customized to solve problems for one specific product/service/etc" can actually be very useful.

That said, I think you're right that you can't really replace an Operations staff, as there will always need to be a human making complex, multi-dimensional decisions around constantly changing scenarios, in order to keep a business operational.
