japan is working on robots to run nursing homes. before they didn't even need nursing homes because homes were multi-generational. your kids just took over running the household at some point and their parents become living nannies who are later taken care of by their kids and grandkids. the same goes for hispanic homes in the united states. but i'm sure that's changing as well since liberal education and indoctrination is destroying their kids' minds as well.
