This is wrong. Waymo uses both lidar and radar, which Tesla opted to remove. Also, look at Waymo's cars. Those things have sensors strapped all over in ways that give them lots of range and visibility. Tesla will never do that because it compromises the aesthetic.

They certainly referred to humans.

Brains aren’t neural nets and eyes aren’t cameras.

Why? The whole idea of neural nets is based on mimicking the brain. It's even in the name: neural (for neuron).

[teraflop]

Yeah, and the name of "Full Self-Driving" tells you that it can drive "by itself" i.e. without human intervention.

But names aren't everything, and artificial neutral networks are "inspired by" but in truth drastically different from human brains.

[colejohnson66]

How so?

[lolinder]

They're different in practically every way. It's easier to enumerate the things they have in common: NNs borrowed the idea of using a connected network of functions whose outputs feed into each other's inputs.

That's it. That's the total resemblance between the two. The brain isn't just an NN implemented in biology, it has whole systems that aren't accounted for in digital NNs, like hormones and neurotransmitters, and even the system of connected neurons doesn't work the way digital NNs implement it.

Neural networks model the brain exactly as well as objects in OOP model cells: not very well at all. They're inspired by biology, nothing more.

[lolinder]

Neural networks as used in AI are inspired by the brain in much the same way that OOP was inspired by the way cells work--neither one is an attempt to faithfully recreate the actual operations of an extremely complex (and only partially understood!) biological system.

I've never met anyone who knew anything at all about neural nets who thought they were mimicking the brain.
