This is a key takeaway: "...we are going to ask YC companies to make whatever data they are comfortable making available to OpenAI. And Elon is also going to figure out what data Tesla and Space X can share." Money is great, openness is great, big name researchers are also a huge plus. But data data data, that could turn out to be very valuable. I don't know if Sam meant that YC companies would be encouraged to contr…

In terms of artificial general intelligence, the kind of stuff that gets associated with 'the singularity' etc. - I agree - there is seemingly nothing at all out there that appears to even be on a trajectory, I mean even theoretically, to coming close. But sure, for more narrow specializations, disrupting certain industries, there is a lot that could be advanced on a short time scale. I don't think the big breakthrou…

That's the thing. It's not necessarily about an evolution. If I "accidentally" make a break though right now. The AI could evolve into a super intelligence before dinner time. Simply stated, an AI that writes AI.(Forget the halting problem for a moment) How many iterations can it create in 3 hours?

> If I "accidentally" make a break though right now. The AI could evolve into a super intelligence before dinner time.

We don't need to rely only on humans to design every aspect of neural networks. We are already computationally searching for AI designs that work better. In a recent paper, hundreds of variations of design for the neuron of the LSTM network have been tried to see which one is the best and which of its components are important.

Also, we can play with networks like clay - starting from already trained networks, we can add new layers, make layers wider, transfer knowledge from one complex network into a simpler one and initialize new networks from old networks so as they don't start from scratch every time. We can download models trained by other groups and just plug them in (see word2vec for example). This makes iterative experimenting and building on previous success much faster.

I don't think evolving a super intelligence will happen by simple accident, it will be an incremental process of search. The next big things I predict will be capable robots and decent dialogue agents.

We still have no clue about the architecture of the human brain. Even if we did, it's not clear we need to replicate it. We do have a clue about the architecture of the human brain. Billions and billions of neurons with orders of magnitude more connections between them. even if we had, say, a million times more flops, and a million times more memory The point is that we could have those things but we don't have a mil…

You would obviously run AIXI: https://wiki.lesswrong.com/wiki/AIXI

We know how to make AI given infinite computing power. That's not really hard. You can solve tons of problems with infinite computing power. All of the real work is optimizing it to work within resource constraints.

Imagine you've programmed a spider-like robot which sole purpose is to maintain some energy level (by plugging into an outlet), gather resources, and create a clone of itself when it has enough resources. How do you defend against something like that?

That isn't really any different from say, a tiger, which is currently facing extinction due to our actions against it.

Yes, I've been just thinking about it, and even without looking at your link, it's easy to see how to build (find) AGI given an infinitely fast computer.

Ok, then, back to the very fast computer.

These drones could be programmed to target specific groups of people, for example of a certain ethnicity, and attack them almost autonomously.

I wrote "almost autonomously".

Admittedly the more interesting part will be the software flying the drone. It seems we are going to need a lot of these [1] and targeted people will need to wear safety goggles.

Actually, unlike controlling humans, whatever that means, it's very easy to limit the impact of AI - all you have to do is treat advanced chip fabrication processes the way nuclear technology is treated, and put a legal limit on processor power so it's somewhere where it was in the late 80s. (So you have office software and email but neither YouTube nor Doom 3; a reasonable price for our survival, I find.) Fewer orga…

>the possibility of extremely cheap drones that approach the victim's face very quickly and pierce a bolt into their brain through one of their eyes.

That's super impractical for many reasons. Drones don't move fast enough, nor can they change their velocity quickly enough to do that. People will almost certainly react if they see the drone coming for them, and cover their face, or swat it down, etc.

But even if it did work, it's not a serious threat. For some reason people spend a ton of time thinking about all the ways new technologies could be abused by terrorists. For some reason they never consider that tons of existing technologies can be abused too.

Many people have come up with really effective terrorist ideas that would kill lots of people, or do lots of damage. The reason the world is still here is because terrorists are really rare, and really incompetent.

> Short range slingshot mechanisms are several orders of magnitude cheaper to build than firearms.

Not necessarily. It's actually not that difficult to make a firearm from simple tools and parts from a hardware store. And it will be way more deadly and accurate than a sling. Not to mention simple pipe bombs and stuff.
