Even if seniors still do the last mile, that’s a significant reduction from the full commute they were paid for previously. Are you saying seniors should concede this?
It's astounding that basically every response you give is just "it can't happen to me". The actual answer to the OP's question for you is a resounding: "nothing".
More or less. I'm just going to enjoy the ride of what becomes of the industry until I either retire or just go do something else with my life.
I already had my panic moment about this like 2 years ago and have calmed down since then. I feel a lot more at peace than I did when I was thinking AGI was right around the corner and trying to plan for a future where no matter what course of action I took to learn new skills to outpace the AI I was already too late with my pivot because the AI would also become capable at doing whatever I was deciding to switch to on a shorter timeline than It would take me to become proficient in it.
If you at all imagine a world where the need for human software engineers legit goes away, then there isn't likely much for you to do in that world anyway. Maybe except become a plumber.
I don't think AGI is this magic silver bullet Silicon Valley thinks it is. I think, like everything in engineering, it's a trade-off, and I think it comes with a very unpalatable caveat. How do you learn once you've run out of data? By making mistakes. End of the day I think it's in the same boat as us, only at least we can be held accountable.
