False. Mining is what uses electricity (and water) in bitcoin, not transactions. Adding more transactions does not add to the cost. Calculating consumption per transaction is misleading as the two are not related.
What does add to the cost is complexity, and complexity is calculated based on number of miners in the network in order to achieve the sweet spot of 1 block every 10 mins (if i remember correctly). If there’s a lot of competition, each miner will have to use more electricity to win.
It’s incorrect. I would comparing to fuel consumption in a car based on how many times you turned. If you make more turns on your way, it would seem your car is more efficient, when in reality there’s very little relation between turns and fuel usage, just like there is little relation between number of blocks mined and transactions.
Knives and car keys are accessible. I don’t know about porn AI tools, i haven’t seen any myself. The AI tools i did see have guard rails that make improper use impossible.
