And by doing that said companies are devaluing their own IP and creating an organizational knowledge debt. Companies that work that way will in long run get outcompeted by shops that figure out (I don't know how) how to manage this better.
I think the opposite, as agents approach human levels of coding and multiple agents work together as a team to code, and check that code in an adversarial manner, companies that do not adopt them will put out less code, of lower quality, for far more money.
There is no mitigation for that situation which would allow human coders to retain their place in the ecosystem.
A man can dig a ditch in a week for £500. 7 men can dig a ditch in a day for £700. 1 man and a digger can dig a ditch in a day for £250.
"But I use knowledge and my brain to do my job, my job is special!"
What's worse, companies might be fine with "devaluing their own IP", since companies are not deciding, execs are.
And those execs will get their bonuses anyway, and will be drinking their champagne far away from their executive roles and the company by the time that's felt.
