That was the prediction when he took a “sabbatical” back in March. Why do people leave companies in this manner?

Employee: I quit. Employer: Are you sure? Why don’t you take some time off and think about it?

This happened to me. I ended up coming back and deciding I still needed to quit, and the CEO was understanding.

Tesla has bet the company on robotaxis, but their vision only tech stack doesn’t seem capable of solving it, which is a problem because Tesla has repeatedly promised FSD is right around the corner, or less than a year away. It’s hard to believe Karpathy would step down if he felt they were close to solving the problem anytime soon. This announcement comes after a 4 month sabbatical where Karpathy said he wanted to ta…

Yeah, but Google's vision + lidar tech also doesn't seem any better at solving it either. They have been working on this problem the longest and they aren't even confident enough to produce a product with it. Google is probably the leader in AI and AI research. They are also the leader in data and mapping. They have billions of cash to play with. Yet it seem like they haven't gotten any closer at solving this problem…

As an owner for 5+ years, the cars show well but pretty quickly become a pain in the ass. They'll get eclipsed by other electric car manufacturers real quick. Edit: more specifically, the parts break and they are difficult to replace. The battery degrades. They stopped providing maps to the vehicle unless I'm willing to spend several hundred dollars to replace the media console, they've told me I'm covered by a recal…

> As an owner for 5+ years, the cars show well but pretty quickly become a pain in the ass. I agree. As a former owner. They are fun to show. But there are real annoyances. In the case of the Model 3 in particular, I quickly tired of the door handles. The psychotic windshield wipers. No CarPlay. The smartphone unlocking which worked most of the time until just that moment when your hands were full. It became a chore…

Given your experiences, I'm curious about your and parent's feedback on the following:

* What are your current top alternative make / models?

* If you have some you're tracking, which make / models are you most anticipating?

Because self-driving has a bunch of tricky edge cases and most of them will kill people. Problems with hundreds of important edge cases cannot be solved by simply throwing more training data at the problem; that's how you solve AI problems in a "dumb" manner, and it works for lots of problems (like recognizing dogs in images) -- but not for self-driving. To solve the self-driving problem we need "smart" A.I., which m…

I disagree with you. On the contrary, I think it can only be solved by throwing more data, but much more data that we have available now, to get first a smart AI that has common sense about the world (a world model). Then we can start trying to drive in it.

I remain convinced that "real" self driving (as in: go ahead and sleep in the backseat) will never happen without changes to road infrastructure and possibly some sort of segregation between robot-driven cars and people-driven cars. Things like traffic signals that actively communicate their status to nearby robot cars (more than just a red lamp that can be occluded by weather, other vehicles, or mud on the camera le…

What you are describing is essentially railway system.

But it is solving the last-mile problem

Cars will never drive themselves.

What's your definition? They certainly do a lot of driving related things pretty well and others quite poorly (much like humans but we have different failure modes).

If you life in San Francisco, CA, you'll often see Cruise cars roaming the streets at night collecting data with no physical driver present.

FSD may be a huge fraud but the whole company is not. The cars are real!

The cars are real but they are... Mediocre. The first year of ownership is an amazing honeymoon period, assuming you got one with decent build quality. But the parts are cheap, and they break quickly. I've had one for 5+ years and it's gradually become something I prefer driving less and less.

they’re electric cars. And i’m pretty sure they’re the biggest electric car brand with the most chargers, which they lease to other automakers at a profit.

My family has a Tesla and they seem to be very happy with it. I’ve driven in it and it seems really nice, maybe not exceptional but not bad.

I do have to say though, the Lidar and self-driving is glitchy and kind of gimmicky. But the fact they’re electric makes them worth it regardless.

> doesn’t seem capable of solving it, How so? If humans can master driving with 2 eyes looking forward, why would a car with plenty of cameras in all directions not have sufficient sensory input to master it? The problem is the software, not the sensors.

not much similar between eyes (incl the full sensory processing) and camera sensors

you're using elon's own argument btw, are you repeating that knowingly

Uber bet the company on robotaxis and lost. Tesla is still building very good cars that happen to not be able to drive themselves. Just like every other car. If they could lose their obsession with self-driving and just focus on their incredible cars, they'd still make money.

> focus on their incredible cars

They have terrible manufacturing quality. The screens melt in Arizona heat. Maybe the ride is cool and feels good, but the car itself is not incredible.

`possibly some sort of segregation between robot-driven cars and people-driven cars.` just build out public transit at that point, what's the difference.
