Do you feel guilty when you break your promise against your cat? Do you even think for a nanosecond if it's ethical to lie to it? Of course, a cat is not conscious. But compared to an AI, we might also be considered pretty low consciousness beings, or at least beings in front of which you don't justify yourself.

> Of course, a cat is not conscious. How do you know?

It's a very good question; I think "of course" is WAY overstating it. I'm interested to know what the GP means when they say "conscious".

In a recent interview [1], Hassabis (DeepMind founder) said they'd try training AlphaGo from scratch next, so it learns from first principles. Without the bootstrapping step of "learn from a database of human games", which introduce human prejudice. As a Go player, I'm really excited to see what kind of play will come from that!

A case of life imitating AI koans: Uncarved block In the days when Sussman was a novice, Minsky once came to him as he sat hacking at the PDP-6. "What are you doing?", asked Minsky. "I am training a randomly wired neural net to play Tic-tac-toe", Sussman replied. "Why is the net wired randomly?", asked Minsky. "I do not want it to have any preconceptions of how to play", Sussman said. Minsky then shut his eyes. "Why…

The actual quote: "Sussman told Minsky that he was using a certain randomizing technique in his program because he didn't want the machine to have any preconceived notions" makes no indication it was a neural net ;)

It's important to remember that this is an accomplishment of humanity, not a defeat. By constructing this AI, we are simply creating another tool for advancing our state of being. (or something like that)

What is our purpose if computers can do everything better than us? It feels like computers have taken one aspect of humanness: logic. Computers could do arithmetic, do algebra, play chess, and now they can play go. It hurts because logic is usually thought to be one of the highest of human characteristics. Yes computers might never be able to replicate emotion, but even dogs have that. There's still some aspects we h…

Do you feel the same way about your human children? Would you rather they were 'better' than you or 'worse'?

Is anyone also asking themselves when they'll be able to play against this level of AI on their mobile phone? Or formulated differently: when will an "AlphaGo" (or equivalent) app appear in the play/app store? In 2 years? In 1 year? In 3 months?

A version of AlphaGo that beat Fan Hui ran on a single machine, but a very beefy one (48 CPUs and 8 GPUs).

Unless they can optimize it quite a bit, we won't be seeing this on a mobile phone anytime soon. Perhaps you'll be able to pay a good hourly rate for the cloud version.

Once again, I am so glad that I caught this on the live-stream because it will be in the history books. The implications of these games are absolutely tremendous. Consider GO: it is a game of sophisticated intuition. We have arguably created something that beats the human brain in its own arena, although the brain and AlphaGO do not use the same underlying mechanisms. And this is the supervised model. Once unsupervis…

> Consider GO: it is a game of sophisticated intuition

It's still a game that can be described in terms of clear state-machine rules. The real challenge for AI is making sense and acting in the real world, which can't be described in such way. I consider advances in self-driving cars much more interesting in that sense - even if, even there, there are at least some rule-based constraints that can be applied to simplify the representation of the "world state".

From watching it I'm almost inclined to say it maximizes its chances of not losing over necessarily winning.

Sorry, but what's the difference?

Through watching those few games, parent has deduced that AlphaGo prefers ties

Well, it would have to have a motivation to do so. Evolution has put complex motivations into human beings for billions of years, self preservation being chief among them. Even if we put motivation for self preservation into an AI, we might not do as well as nature did, leaving the AI open to self destruction or shutdown by humans - simply because the AI has no motivation not to allow humans to turn it off. Human des…

If an AI has any motivation at all, say, to make paperclips as efficiently as possible, then any threat to its existence is a threat to its objective function - namely, to create paperclips. A hyper-intelligent entity who is instructed to optimize for paperclips created will therefore proactively remove threats to its existence (i.e. its paperclip-creating functionality) and might possibly turn the entire solar syste…

Always check your loop invariants very carefully.
