The Lighthill debate on Artificial Intelligence: "The general purpose robot is a mirage"
Why Hacker News recommends it
HN cites it as primary-source history of AI hype and skepticism, and for the vintage Freddy robot footage.
What it is
The full 1973 BBC Lighthill debate on artificial intelligence, featuring James Lighthill, Donald Michie, Richard Gregory and John McCarthy. It documents the argument that preceded the 1970s AI winter and includes early robot demos.

Anyone interested in the History of AI can also watch the report being presented by Lighthill, and subsequently debated by John McCarthy, Donald Michie, and Richard Gregory. [this video]

> ... "AI can't do X" until we actually achieve X and then the goalpost is moved. This gets said often but I don't think anybody whose credible in the field actually makes statements like this. Take Chess for instance. In the IBM "Big Blue" documentary from ~2004, they quote journalists as saying "AI can't play Chess as well as humans but if it could, then AI would be solved." Why did the techniques from Big Blue not seem to go anywhere? I know for a fact that scientists _were not saying this_. The Lighthill Debates on AI specifically talk about why playing games well doesn't really prove anything. [0] I do agree that OCR has improved greatly by AI but this feels very niche.

To be honest, 89-92% sounds too optimistic for a real-world application. But I was talking about applications of the lego assembly model. My intuition is that lego is a special case: the pieces are made to interlock with each other and there are only a small number of ways in which two pieces can lock together. Compare this with building a prefab house, for example, or a car, where elements must be bound together with nails, mortar, soldering, or glue etc, in essentially unpredictable ways. I say that the approach described is pointless because I can't see any real-world applications of extracting assembly plans from a visualisation of an already-known assembly plan. Even less so when the ob

I'd like you to view this demo from 1974 that showcases the then current state of research in AI. Then reflect that the research presented in the link is 50 years later. [this video]

Nice robot demo. Here's another one: [this video] A robot assembling a puzzle with machine vision! And it's only from the 1970's.
