How fucking bizarre that your nationalist brain rot oozed into a completely unnecessary scenario. You start by stating that theres nuclear radiation outside so you live 30ft under ground. Then proceed to bitch about people speaking 50 different languages on the surface because immigration has gone out of control. You're literally just a miserable little boy.

What you actually just described is your future experience of drifting into dementia. You'll be alone in your dark one bedroom, you'll hear laughter and fun happening outside, humans living the true human experience. You'll sit there with the glow of your monitor, prompting the same dark fantasies into existence, over and over again, until it's become a monotonous repetition that drives you to complete insanity. Your government care taker android will arrive each day with your "stashes of preserved food". Life is good.
