Because it's beta, you are supposed to maintain attention and control as you would driving normally. Thus, there's no extra danger, issues are generally on the driver.

If the driver fell asleep, or didn't see a car, that happens all the time with human drivers. Beta FSD will save most of them from themselves, but it may miss a few.

My point is that the Soviets mastered this design almost 50 years ago, yet BO is having problems doing it just with a different fuel. Nobody's ever mastered full-flow staged combustion (didn't go beyond testing), yet SpaceX appears further along with that than BE-4, in about the same amount of time. My bet is that it's mostly management issues.

Edit: New news: ULA is having problems qualifying one of the engines for flight because it keeps pumping out too much oxygen. You'd think BO would at least have something like this right before they shipped, but apparently the engines had only minimal testing.

I like SpaceX, but I don't want them being the only cheap, reusable medium+ launch service out there. BO needs to get its act together.

They lit 31 engines, a world record. The last time someone tried 30 they blew up four rockets in a row, the second one destroying the launch facility.

>IIRC it also started development before the BE-4

They were kind of playing around with ideas before BE-4, but real design didn't start until around the same time.

>if we ignore that a full flow staged combustion engine also has an oxygen-rich side

We'd have to. It's amazing to me that a modern company absolutely flush with cash is having serious issues designing roughly a methane variant of what's just a dual-chamber version of what was at the time a 25+ year-old engine. Something's been very wrong at BO. I'm just hoping now that Bezos is actively involved they can clean up their act.

I wonder why they had so many problems with that engine, slipping the deadline again and again. Really, it's yet another oxygen-rich staged combustion engine, even simpler than the dual-chamber RD-180 it replaces. The Raptor is doing fine, and it's a much more complicated engine to engineer (full flow staged combustion).

That might apply to a McDonald's worker, but not here. They only had jobs in the first place because of AI. It's abusive because they knew their jobs were temporary, and they're using a unionization attempt to artificially extend them.

Putting them in other jobs would be a good idea, but these are pretty low-talent jobs. Look at an image on a computer, tell the computer what it is, next image. Google has been using us to tag images through captchas for years.

Tesla always planned for the human labeling to exist only until it wasn't needed anymore, because at some point you will have done enough labeling and the supercomputers can take it from there. They already announced cuts in labeling last year. These people already knew their jobs had an end date not too far out. It sounds like they may have started unionizing just to put a legal wrench into the plans. I'm okay with unions, but this sounds like an abuse of union laws.
