Why would it concern a PE. 99.9% of their job is already stuff someone else could do and would rather not pay them to do but the government forces them to anyway. AI doesn't change that except perhaps remove a bit of the plausible deniability.

Now, I know, I know, I'm about to be hit with some bad faith retort about skyscrapers and bridges and other things engineered on a fine margin falling down. Your average multi tenant commercial building, your average parking lot, your average retaining wall ain't that. And that's the stuff that's the bulk of what PE firms do.

Because there are thousand of PEs across the country and eventually if a job requires 100x less time to produce, PEs will just be rubber stamping stuff after a thorough final review. My firm has like a dozen electrical PEs and we all spend the vast majority of our time in coordination meetings, reviewing small details, and working on drawings. If all I have to do is spend a few hours checking something at the end, they don't need all of us for that anymore.
