The following is a conversation with Doug Lennett, creator of Psych, a system that for close to 40 years

0:07.5

and still today has sought to solve the core problem of artificial intelligence,

0:12.8

the acquisition of common sense knowledge and the use of that knowledge to think, to reason

0:18.9

and to understand the world. To support this podcast, please check out our sponsors in the description.

0:24.4

As a side note, let me say that in the excitement of the modern era of machine learning, it is easy

0:30.6

to forget just how little we understand exactly how to build the kind of intelligence that matches

0:37.4

the power of the human mind. To me, many of the core ideas behind Psych, in some form,

0:43.6

in actuality or in spirit, will likely be part of the AI system that achieves general superintelligence.

0:50.4

But perhaps more importantly, solving this problem of common sense knowledge will help us humans

0:56.5

understand our own minds, the nature of truth, and finally, how to be more rational and more kind to each other.

1:23.4

1:29.5

I use the Squarespace to create Gogginschallenge.com back in the spring for the 4x4x48 challenge,

1:38.0

where you run 4 miles every four hours for 48 hours, so it ends up being 48 miles.

1:44.0

It literally took a few minutes to create the website, where there was a form where people

1:48.4

could submit their story, leading up and after the challenge, and also I was able to provide basic

1:54.2

information about one of the challenges and so on. David Goggins asked me if I could do it real quick,

1:58.9

I said no problem, got it done. Squarespace is the reason I could do it so fast, and the final

2:05.8

result looks pretty good. I think we put the website on hold for a while until the next David Goggins

2:12.7

challenge. Like I said, I think it's great for one-off events and major personal sites,
