Why? They've made this all available, why is grabbing it all in increase your own convenience (eg offline reading, searching) rude ?

Because when you actually read it, you will download 1 article per 30 minutes. If you batch-download all of their content now, you'll create much more peak load and, hence, costs for them.

So read the wget man page and add settings to your liking:

--wait=5000 --random-wait

Done...

Wikipedia has an interesting list of cognitive biases [1]. Going through these, I tend to think of all of them as heuristic failures, where those shortcuts and incomplete solutions are pushed to edge cases.

I’d take the other side of that strongly, if it was possible. The human brain is definitely not a kludge by any definition. And a lot of the tricks people think they know are not tricks at all.

Neuroscientists are the new doctors of the 50s. We thought the appendix was useless turns out it has many uses. We thought priming and all these “tricks” were things and then the crisis and Kahneman et al were debunked.

I bet the brain is just as elegant and powerful as it has to be to do the incredible complex things we do, and we’re just so far from really understanding it that we run around appendicizing all sorts of things we just don’t really know well yet.

But no more than that. Which is what Minsky was saying.

Not at all. Kludge being the operative word. I claim the brain is fantastically not kludgy. It has incredibly flexibility, adaptiveness and no duct tape or shortcuts. It “has to be” incredibly good at so many things - it’s basically the perfect general computation machine. It “has to be” not kludgy. Minsky is part of an era where scientists were all about showing how humans were easily fallible and much of that was debunked.

Sorry but you’re not following my point or his if you think they agree.

Why can't it be both? Maybe the duct tape and shortcuts are what give the human brain it's fantastic adaptability. Duct tape and shortcuts aren't a bad thing necessarily. Personally, I think that's what gives the human race as a whole it's fantastic adaptability. You've got millions of people each with their own duct tape and shortcuts to the same problems, meaning each of us does things just a little bit differently, we see other humans with their shortcuts and slap them onto our own with some duct tape and we get better at things or learn something new. Do this over millions of years and generations and you've got a pretty damn capable brain that's slapped together millions of years worth duct taped together solutions and skills that keep growing as we hand our giant ball of duct tape to successive generations.

I've been thinking a lot about trying to make an AI for a turn based 4X game. I believe an AI that could defeat the strongest human players in (for example) Civilization would be more impressive than AlphaStar and the Dota AIs.

I think it might give the gaming industry a kick in the pants to start utilizing more advance AI techniques in general, since it seems almost all discussions of strong AI in games are dominated by apologists explaining why it's not practical. Just one example of strong AI in a successful game would change the industry.

After strong AIs are common, we can persue the even more interesting task of dumbing them down in fun ways.

> Unfortunately, the time between seeing a decision acted out and the actual act of making that decision can mean that all relevant information has already been discarded. Ideally if the entire game simu-lation could be rewound to the exact moment in time when the error occurred, it would make notoriously difficult problems to debug, trivial to understand why they occurred.

> Game engines have typically made reproducing these types of problems easier using deterministic playback methods (Dickinson 2001), where the entire state of the game simu-lation can jump back in time and resimulate the same problem over and over (Llopis 2008).

Imagine if you could do this for all programming? [from chapter 6]

I just don’t think in millions of years of evolution the shortcuts are what worked. I think our brains are the result of non shortcuts winning over a long period of time.

It is funny how willing computer scientists are to want to use a duct tape analogy. I think it’s because programming, which is basically the polar opposite of a brain (precise and unintelligent) requires so much damn duct tape if you want to get anywhere useful. Meanwhile a brain literally requires as little duct tape as possible if you want it to be generally good.
