>> I wonder how this will work in practice. Say I'm a senior engineer and I produce myself thousands of lines of code per day with the help of LLMs as mandated by the company.

LOL, it's the age old "responsibility without authority". The pressure to use AI will increase and basically you'll be fired for not using it. Simultaneously with the pressure to take the blame when AI fucks up and you can't keep up with the bullshit, leading you to get fired. One way or the other, get some training on how to stack shelves at the supermarket because that's how our future looks, one way or the other.
