Answering the question in the image: machine learning arose from the industrial control world. The idea was to teach a machine how to detect defects in supposedly identical objects out of a manufacturing line, most often with “machine vision” (ie. a camera). Applying it to humans was asinine.
Modern houses with their insulated walls and double windows are better at withstanding summer than the ones I’ve lived in while my only solace for 85+ degree nights was a fan.
I’m all for demanding proper maintenance from landlords, even if it’s not on the lease. You visit a unit that has a thermostat on it, that’s advertising it has a working AC. It’s disingenuous from the landlord to claim the AC is decorative.
But claiming air conditioning is essential is utter horseshit.
