I had this happen many years ago, to the point there was no chance something wasn’t listening. We suspected it was my partners iPhone with Facebook installed before they got better about preventing abuse like that, as it was a Facebook ad that showed up.
Were talking about something where we never use the product, would never use the product, but it came up in a conversation just between the 2 of us, and there were ads the next day.
It happened a few times.



I read a story of one datacenter years ago where their waste heat was heating the industrial complex around them. It was a nice change to see. Regulations around it would really help. Oh you want to do this? You need to reuse 80% of your waste heat to get approval, and have x% of power be renewable.
We know how do it, people just dont.
