When I have gotten time to do something deeply technical, even that time isn't spent on writing code. I've spent hundreds of hours in labs with colleagues debugging complicated systems trying to track down where a single code line change needs to be made. The ratio there is probably 1 line of code written per two dozen hours spent testing and debugging.
AI has little to no value in any of that. If companies really want to save money, their leaving billions on the table in operational inefficiencies, compared to a few thousand dollars in incremental improvements to developer productivity.
