Nonsense. People are universal explainers, unlimited progress is possible. Read "The Beginning of Infinity" by David Deutsch.
- What’s the issue with logic, reason and science? Name one case where using them less would be better.
- We don’t put faith in them. That would itself be illogical, unreasonable and unscientific. Faith means “don’t ask questions”.

Is this a little bit like life? And if so, would understanding the origin of life help us understand how creativity works, and vice versa?

The creative algorithm was originally used to replicate memes. When turned on itself, it tries to replicate creativity (e.g. in AGI research); it tries to replicate itself.

As in “falsifiable by observation”? It can’t be. It’s a philosophical principle. You can criticize it, though.
@ChipkinLogan @DavidDeutschOxf
We should expect our theories to contain mistakes. Problems with constructor theory may sooner or later be discovered, which will require an even better/deeper explanation. There are no “final” theories.
@dela3499 @DavidDeutschOxf @dautingthomas
Yeah I wonder what an example would be as well. Up until now I thought there was only one universal creativity. Is it that there would be a difference in code quality across different implementations of creativity?

Love me some Debussy Delight. I also recommend Stravinsky Strudel.
As an individual’s knowledge grows, so does the amount of information he can use to create new explanations. Therefore, I would expect his creation of new knowledge to get slower over time. Yet we don’t seem to observe that. How can we explain that?
Oooh I love listening to new material of his. Thanks for sharing!
None? My phone can recognize me, too. I don’t think it’s conscious.
Damn, that’s cray cray in a good way right there!
I still don’t get it. Why do we need an alternative theory to falsify another? If I have a theory and any one of its predictions doesn’t come true, the entire theory is refuted by modus tollens alone, no?
Can you please elaborate on “Theories don’t need to be falsifiable to be science.” They need to be hard to vary, but also falsifiable, no?

Regrettably, yes. The three stages of adopting critical rationalism that I’ve observed: 1) “Anything that’s not induction is stupid or navel gazing” 2) “Actually, this is neat!” moves on to something else 3) “Holy shit this is amazing and I’ll apply it” Few make it to 3 :(
Agree with Brett here. I’ve read four or five of Popper’s books and still struggle with LScD. My first Popper book was “All Life is Problem Solving”, after I read BoI and FoR (in that order). I think it’s the last book he published before his death. It’s great!

Not to mince words, but I wonder if we should distinguish self awareness from self recognition? Self recognition is the thing we could easily program today, whereas self awareness requires creativity.

Given what the announcer said moments before, it seems to me he’s just restating the final anthropic principle. But I can’t say for sure.
A friend from college and I would watch many episodes of South Park and a few animes (Death Note, Elfenlied, and others) that way. We’d talk on Skype and play the video at the same time and he would usually mute his video while listenting to my sound.
That’s not true. You don’t know what to observe without some hypothesis of what to look for and where something of interest might be.
I don’t disagree though that we should always try to falsify theories and demand good corroborating evidence, the absence of which leaves a theory vacuous.
I’d agree here with @jeffreyketland’s remark. Also I’d argue that science begins with problems and the quest for good explanations.
Eg Newtonian physics is still very useful and explains many things in certain contexts where relativity would be overkill to use, even though relativity is of course the better explanation. 2/2
I haven’t read Lakatos, but they may indeed uphold even a falsified theory if it has good explanatory power. 1/2

Wow @ChrHansen your team has gotten so big! Congratulations!!
I like the emphasis on conjectures and refutations. Yet sometimes in interviews you say that we should consider something false until proven true. How do you reconcile these two approaches? (The difference being that conjectures in the Popperian sense can never be proven true.)
Are you working on a new book? Please say yes. :)

"[Euclid] put into his book only those problems that he could solve. And this, in a certain sense, was a crime."
I LOVE that :)
So would you say machine learning is orthogonal to AGI? Or does it contribute in some way?
@mattguttmanorg @DavidDeutschOxf
I don't think that's true. @DavidDeutschOxf provides a good explanation of why behaviorism is not a good epistemic frame. See aeon.co/essays/how-clo… Don't mean to put words in his mouth though if I'm wrong in this particular context!
5/5 And each time this is done through conjecture and criticism. And then the cycle continues. Does this not seem Popperian? If it is, it seems to me we have made at least some headway in trying to code up AGI, but we'd need to do it for more than just mathematical problems.
4/5 In this example, the first problem is "We don't have an explanation for how the planets move", to which the conjectured explanation is Kepler's laws. The second problem is the observation that they're not accurate enough, and so the laws are improved, etc.
3/5 Then, if there is a problematic observation (problematic = it cannot be derived from Kepler's laws, such as a planetary position that does not fit the model), then the symbolic regression runs again given the problem, and it may find better explanations than Kepler's.
2/5 What I mean is, eg, symbolic regression can find Kepler's laws given data about planetary positions etc. And it does so through conjecture and criticism, since it's a genetic algorithm. I think John Koza may actually have done this for Kepler's third law, but I'm not sure.
1/5 We are on the same page about science being a process of conjecture and criticism that starts with problems.
I recently stumbled upon the concept symbolic regressions. Seems related to Popperian epistemology and explanations. Is being a universal explainer the same as being able to construct universal symbolic regressions (as opposed to just mathematical ones)?
It says the video is unavailable (for me at least).
What's your take on machine learning? It strikes me as induction applied to computer engineering and if I had to guess it does not bring us one step closer to general AI, but I'm curious if that's false.

In the "Logic of Scientific Discovery" chapter 1 section 2, Popper conjectures that intuition plays an important role in coming up with new explanations (creativity). He also quotes Einstein as corroborating this in his address at Planck's 60th birthday.

Instead, he describes the process of conjecture and criticism by which theories can be dismissed. Surviving theories are nonetheless unlikely to be true. That likelihood does not improve with more failed tests. (See Logic of Scientific Discovery, Popper, 1934) 2/2
Loved your book "The Emperor of All Maladies" - just one minor suggestion for improvement. Popper does not describe the process by which scientists "verify" theories. And theories do not gain credibility or robustness when attempts to falsify them fail. 1/2

It is my understanding that to apply knowledge, one has to have knowledge that said knowledge exists in one’s mind. But one has to have knowledge of that second knowledge too, etc. An infinite regress?
