If you can do inspections then you can already do a similar level of teleoperation to the GPS driving example, where the computer is planning the behavior of a human who is already skilled at the task. “Do the thing” followed by “fix this issue”, “fix that issue”, etc.
It‘s not obvious to me that the economic incentives would lead to applying that capability for inspections before applying it for teleoperation itself, so I think inspections are not actually a reliable canary.
It’s not clear to me why the regulatory and permitting hurdles would be lower for the established company that starts using teleoperation than for a new company doing the same thing. Maybe the new company gets slightly faster scrutiny if they start doing illegal stuff? But if an established company’s permit filing rates go down without a clear explanation or they start replacing licensed labor with teleoperated labor on permitted projects, that’s still going to be noticed quickly.
That said, I do agree that consumer reputation effects mean that the biggest impacts happen when these practices become widespread across established companies. I don’t think that necessarily takes super long though; if there’s efficiency to be had, then the current wave of private equity buyouts of established businesses in the trades will simply accelerate. Funds will be able to buy existing companies at a premium to their current fundamentals, change the existing firms’ business practices to crank up their profits, and either keep the resulting revenue stream or flip the business for a quick profit.
