I was horrified/entertained by the 'Grand Designs' episode on TV here last night. A British tech bro discovers he can't afford his obscene "castle", when his credit runs out after borrowing millions.
His main product seems to be a light switch, part of a smart home system which remains largely vapourware. His business and his grand design frequently mention "sustainability", while wasting massive amounts of concrete, water, electricity and data centre tokens for meaningless extravagance.
