Well done Lex. He doesn't get it. But keep calm and carry on (as they say here in the UK),(reply>), @archie "Jim is one of the most respected Chip designer in the world."<br>Andrew Ng is one of the most respected AI experts in the world. Probably his opinion would be irrelevant on chip design questions, like instruction pipelines.,(reply>), Okay. I’ve listened to it again and decided he definitely doesn’t know what he’s talking about. He mentions remembering specific pot holes and remembering specific roads and getting updates to learn about changes to specific road conditions. This is not how autonomous systems work at all, they’re generalised and can work on any road regardless of whether they’ve seen it before. Though maps are obviously required for navigation, but that’s not what he’s talking about.,(reply>), Kusa Weir Yes he is too pessimistic. Though driver monitoring is probably a boring but useful step whilst autonomous systems are good but not perfect. We’ll start to trust them before they’re ready to completely take over.,(reply>), @archie I can't imagine chip design has much crossover with designing and implementing deep learning systems. I work as a data scientist in computer vision and I agree with Lex when he says vision  is harder than people think. Perception systems are incredibly brittle, particularly around dealing with occlusion which involves a lot of understanding of the world that we take for granted - as Lex mentioned. Don't forget, Lex is a leading researcher and I'd go as far as saying expert in autonomous system design himself. I still think we'll get there in 5 years or so.,(reply>), Lex is too pessimistic on this problem. Let's not forget, he spent a huge amount of time working on driver monitoring. A total dead end.
