In his own words.

“Initial production is always very slow and follows an S-curve. The speed of the production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”

“Could be wrong, but I think AI5 will probably be the best inference chip of any kind for models below ~250B params. By far lowest cost silicon and best performance/Watt. AI6 will take that much further.”

“The Blindsight device from Neuralink will enable even those who have lost both eyes and their optic nerve to see. Provided the visual cortex is intact, it will even enable those who have been blind from birth to see for the first time.”

“Traffic is driving me nuts. Am going to build a tunnel boring machine and just start digging...”

“Join @xAI and help build a purely AI software company called MACROHARD. It's a tongue-in-cheek name, but the project is very real! In principle, given that software companies like Microsoft do not themselves manufacture any physical hardware, it should be possible to simulate them entirely with AI.”

“Once in production, we expect that Cybercab will begin to replace the existing Model Y fleet and will be the largest volume vehicle in the fleet over time.”

“We're going to make this.”

“Tesla Semi starts high volume production this year”

“You want to wake up in the morning and think the future is going to be great - and that's what being a space-faring civilization is all about.

“When you have a large fleet of vehicles, you can gather a lot of data about how the world works, and that data is incredibly valuable for training neural nets.”

“You boil things down to the most fundamental truths and say, okay, what are we sure is true? And then reason up from there.”

“The best part is no part. The best process is no process. It weighs nothing. Costs nothing. Can't go wrong.”

“When something is important enough, you do it even if the odds are not in your favor.”

“Failure is an option here. If things are not failing, you are not innovating enough.”

“Persistence is very important. You should not give up unless you are forced to give up.”

“I think we should be very careful about artificial intelligence. If I were to guess at what our biggest existential threat is, it's probably that.”

“Our goal when we created Tesla a decade ago was the same as it is today: to accelerate the advent of sustainable transport by bringing compelling mass market electric cars to market as soon as possible.”

“Short of figuring out real teleportation, which would of course be awesome, the only option for super fast travel is to build a tube over or under the ground that contains a special environment.”

“Will still transport cars, but only after all personalized mass transit needs are met. It's a matter of courtesy & fairness. If someone can't afford a car, they should go first.”

“Boring Co urban loop system would have 1000s of small stations the size of a single parking space that take you very close to your destination & blend seamlessly into the fabric of a city, rather than a small number of big stations like a subway”

“Tunnels under cities with self-driving electric cars will feel like warp drive”
