I mean that if an AI can make me more productive then I can tackle those TODOs , I agree you can't just hire a new dev for those tasks because he will need training in our code base,t hat will cause me to waste more time training , explaining , debating stuff. Anm AI could help with boring crap like I could ask it to review my code for potential bugs, maybe write some tests, in future it could refactor some bad code to be more clear , like better variable names, split it in smaller functions, replace deprecated syntax and function with latest stuff.

I think only a company with serious money issue would fire a good developer that you trained for years in your code base instead of letting him to focus on the TODOs/bugs and get things fixed and new features at a faster speed.
