I would even recommend against going back to college unless someone has an extremely compelling case for a career change that requires it and the conviction to see it through.
I'm hesitant to give examples because I know every example I give will be met with objections from "But I don't want to do that job" or "What if that gets replaced by AI too?". Look around you and you can should be able to identify some adjacent roles where you at least have an understanding of what the works like and you could learn the rest by taking on gradually more responsibility.
There are a lot of jobs out there that aren't exciting, don't pay SWE level salaries, but nevertheless pay enough to support a family as evidenced by all of the people doing those jobs who support their families. Not every company or industry is interested in squeezing maximum efficiency out of their employees. I have friends in highly bureaucratic roles who care about their jobs and do it well, but their work is amazing simple and easy. It requires nothing more than being a responsible adult who can show up to the office and get things done. These jobs are everywhere and I don't think they're going to disappear.
I don't think SWE is going to disappear either, but it will look a lot different in years to come. If you can't or won't adapt to the new normal, one of those boring alternative careers might be worth pursuing.
