Tesla disagrees. Full Self Driving is coming in 2015 ergh 2016 ergh 2017 ergh 2018 ergh 2019 ergh.. end of 2020...
Now the Tesla fanboys are saying that it will come in 2021.
Just look at the world we live in: it contains 6 billion people. If a small fraction of it is into buying a car or a game that will only work as advertised a decade after they buy it, you might still be able to sell the millions of cars, games, etc.
If you check out the news, the amount of people that's delusional is not a "small fraction", but actually closer to ~50% of the population.
Sure you do, because we're moving to a new type of reality whereby software is a determinant of features. A lot of people haven't gotten the memo on this yet though.
All Tesla vehicles ship with everything necessary for Autopilot, all the hardware and sensors. If you want to turn it on, you just unlock it with software. Tesla vehicles also get feature updates regularly.
Computer hardware has been this way for awhile. NVIDIA specifically has a history of improving the performance of their GPUs simply with new driver updates, in some cases with ridiculous performance gains on the order of 7-10%. Just from software optimization.
A video game is purely software, so the optimization limits are truly limited only by the hardware upon which it is run and stored.
But you don't buy a new car and say "in six months this is going to be a great car" - you have expectations when you put the money down...
