alt Hacker NewsAccording to Elon, "sensor ambiguity" is a danger to the process [1], and therefore only a single type of sensor is allowed. (Conveniently ignores that there can be ambiguity/disagreement between two instances of the same type of sensor)
The fact that people still trust him on literally anything boggles my mind.

Sensor ambiguity is straight up useful as it can allow you to extract signals that neither sensor can fully capture. This is like... basic stuff too, absolutely wild how he's the richest person in the world and considered this absolute genius
Truly. I don't understand why Tesla fans think camera/lidar fusion is unsolvable but camera/camera fusion is a non-issue.
Personally as much as people like to dunk on Musk, he did build several successful companies in extremely challenging domains, and he probably listens to the world-leading domain experts in his employ.
So while he might turn out to be wrong, I don't think his opininon is uninformed.
I certainly don't trust anything he says 100%.
This is - to me - entirely separate from the fact that his companies routinely revolutionize industries.

Long-distance amateur psychology question: I wonder if he's convinced himself that he's a smart guy, after all he's got 12 digits in his net worth, "How would that have been possible if I were an idiot?".
Anyway, ego protection is how people still defend things like the Maga regime, or the genocide; it's hard for someone to admit that they've been stupid enough to have been fooled to vote for "Idi Amin in whiteface" (term coined by Literature Nobel Prize winner Wole Soyinka), or that the "nation's right to self-defense" they've been defending was a thin excuse for mass murder of innocents.
Well, given that Elon openly lies on investor calls...
One of his latest, on the topic of rain/snow/mist/fog and handling with cameras:
"Well, we have made that a non-issue as we actually do photon counting in the cameras, which solves that problem."
No, Elon, you don't. For two reasons: reason one, part A, the types of cameras that do photon counting don't work well for normal 'vision'/imagery associated with cameras, and part B, are not actually present in your cars at all. And reason two, photon counting requires the camera being in an enclosed space to work, which cars on the road ... aren't.
What Elon has mastered the art of is making statements that sound informed, pass the BS detector of laypeople, and optionally are also plausibly deniable if actually called out by an SME.
If only there was a filter so we could fuse different sensor measurements into a better whole..
Sensor fusion allows you to resolve that ambiguity, I wonder if Elon is really as in touch with this as you would expect. No single sensor is perfect, they all have their problematic areas and a good sensor fusion scheme allows you to have your sensors reinforce each other in such a way that each operates as close as possible to their area of strength.
No single sensor can ever give you that kind of resilience. Sure, it is easy in that you never have ambiguity, but that means that when you're wrong there is also nothing to catch you to indicate something might be up.
This goes for any system where you have such a limited set of inputs that you never reach quorum the basic idea is to have enough sensors that you always have quorum, and to treat the absence of quorum as a very high priority failure.
