I'm thinking of some similarity between the non-technical middle manager using agents to avoid the biggest obstacle of their developers, and a person installing a wall socket at home.

It's not too difficult to install a wall socket, but many things can go wrong, so people would normally call an electrician. In some jurisdictions you are not allowed to install it without a license, or probably you can install it only for yourself but not for anyone else if you don't have a license, and you need to call an inspector and check your work when you're done. Some other jurisdictions truly don't care, you can do whatever, and all the possible damage is on you.

Electricians are somewhat fungible, because you often don't care who will do the job for you, but the profession exists and they can pay their bills.

I wonder how far we are until, at least in some jurisdictions, a person won't be legally allowed to update the website that stores customers' data or processes payments without being a licensed software developer, and how rules, should they be adopted, will change our profession.
