If we abdicate and let all software development and operations occur through the use of fully autonomous agents, someone is still ultimately responsible for the agents work/screw-ups. Thus, there is still a human writing code, from an ownership perspective. We all know it won't be the capital/manager class holding the stick there.
That isn't what "writing code" means. The responsibility is for using the AI, or being negligent in doing so, but the AI is obviously writing the code. That's the entire point of it.
Unfortunately, it's not super easy for me to migrate away from Proton, but it's the next personal tech project I'll undertake.
