I'd think that depends on the model of responsibility at play.

For example, suppose I hire a building contractor to build a house, and the electrician he subcontracts makes mistake.

From my perspective, the prime contractor is equally responsible for that mistake regardless of whether he used a subcontractor, or did the work himself but used a broken tool.

This doesn't make the electrician any less of a "person" in the deeply important ways, but it's not a distinction that's relevant to my handling of the problem.

So you figure out that someone you paid is at fault, instead of someone they hired. Your contract is with them so what really changes? What process or anything else is really different between it being a company with a manager who asks a team of devs and a company which asks an AI agent, to you as a customer?

Maybe it changes who gets fired or sued or whether one insurance or another pays out- but broadly I think none of what I said about project work really changes.

Product owners and hell even customers have been able to get software they don’t understand all the details of or for customers even get to see the code, purely driven with natural language.
