I can see why someone might be confused, this was Elon's quote from the last Earnings Call:

I think there's also some potential here for an AWS element down the road where if we've got very powerful inference because we've got a Hardware 3 in the cars, but now all cars are being made with Hardware 4. Hardware 5 is pretty much designed and should be in cars, hopefully toward the end of next year. And there's a potential to run -- when the car is not moving to actually run distributed inference.

So, kind of like AWS, but distributed inference. Like it takes a lot of computers to train an AI model, but many orders of magnitude less compute to run it. So, if you can imagine future, perhaps where there's a fleet of 100 million Teslas, and on average, they've got like maybe a kilowatt of inference compute. That's 100 gigawatts of inference compute distributed all around the world.
