Children sticking around isn't the only option. My mom intends to follow me once I've found a place to settle down in the next few years. I'll give her extra money which should allow her to live quite well on top of what she has saved and she's already expressed interest in helping with grandkids if I have any (I probably will at some point).

Obviously this plan is made much easier by remote work and good earning potential for tech workers and I suppose some parents will be more attached to where they currently live than my mom is. But multi-generational is not outright impossible, I'd wager a significant chunk of the population could pull it off to varying degrees in one way or another.
