George Hotz: Elon is the iOS | AI Podcast Clips
00:00:00.000 | (gentle music)
00:00:02.580 | Elon's the iOS.
00:00:09.440 | By the way, he paved the way for all of us.
00:00:11.960 | - Right, it's the iOS, true.
00:00:13.280 | - I would not be doing comma AI today
00:00:16.160 | if it was not for those conversations with Elon
00:00:18.760 | and if it were not for him saying,
00:00:21.440 | I think he said, "Well, obviously,
00:00:23.640 | "we're not gonna use LiDAR, we use cameras.
00:00:24.960 | "Humans use cameras."
00:00:26.600 | - So what do you think about that?
00:00:27.560 | How important is LiDAR?
00:00:29.200 | Everybody else on L5 is using LiDAR.
00:00:32.280 | What are your thoughts on his provocative statement
00:00:34.520 | that LiDAR is a crutch?
00:00:36.680 | - See, sometimes he'll say dumb things
00:00:38.400 | like the driver monitoring thing,
00:00:39.400 | but sometimes he'll say absolutely,
00:00:41.040 | completely, 100% obviously true things.
00:00:43.720 | Of course, LiDAR is a crutch.
00:00:45.200 | It's not even a good crutch.
00:00:48.360 | You're not even using it,
00:00:49.200 | oh, they're using it for localization,
00:00:51.360 | which isn't good in the first place.
00:00:53.500 | If you have to localize your car to centimeters
00:00:55.840 | in order to drive,
00:00:58.280 | yeah, they're not-- - That's not driving.
00:00:59.600 | - Currently not doing much machine learning
00:01:01.600 | on top of LiDAR data,
00:01:02.880 | meaning like to help you in the task of,
00:01:06.640 | general task of perception.
00:01:08.160 | - The main goal of those LiDARs on those cars,
00:01:10.640 | I think is actually localization more than perception,
00:01:14.160 | or at least that's what they use them for.
00:01:15.400 | - Yeah, that's true.
00:01:16.220 | - If you wanna localize to centimeters,
00:01:17.800 | you can't use GPS.
00:01:19.000 | The fanciest GPS in the world can't do it,
00:01:20.440 | especially if you're under tree cover and stuff.
00:01:22.240 | With LiDAR, you can do this pretty easily.
00:01:23.760 | - So you really, they're not taking on,
00:01:25.520 | I mean, in some research,
00:01:27.160 | they're using it for perception,
00:01:29.080 | and they're certainly not, which is sad,
00:01:31.120 | they're not fusing it well with vision.
00:01:33.960 | - They do use it for perception.
00:01:35.840 | I'm not saying they don't use it for perception,
00:01:37.680 | but the thing that,
00:01:39.320 | they have vision-based and radar-based
00:01:41.360 | perception systems as well.
00:01:42.960 | You could remove the LiDAR
00:01:44.720 | and keep around a lot of the dynamic object perception.
00:01:49.320 | You wanna get centimeter accurate localization,
00:01:51.600 | good luck doing that with anything else.
