My ML prof in university used this as an example for something that could happen but is highly unlikely. Each particle of oxygen can be in either half of the room so it's like 1/2 to the power of the number of particles (avogardo?) chance that all the particles are in one half suffocating the ppl in the other half. He was such a great guy.
This is a good point. Did Kagi ever consider having a freemium tier that uses adverts to pay for the (search) content? I don't think it is a terrible idea if it helps Kagi to improve their paid search.
Both are technically possible, but so extremely unlikely, that you can rely on them not happening.
