I've been dreaming of creating a platform that used crowd sourcing to map concept & procedural masteries to higher level masteries and to occupations. Basically, a giant graph database mapping concepts, procedures, systems (versioned), and occupations. I think such a database could be used to improve learning management systems for school faculty and autodidacts alike. It could also serve as the basis for a performan…

Glad to hear that someone else finds this direction interesting. I actually built something in that direction half a year ago: https://owleo.com

But I mostly abandoned it for now, as expii.com seems to be pretty close to what I wanted to have. Also since I finished my studies, my learning changed to be more explorative and need-driven, which didn't fit well into the thinking behind Owleo.

Natural language understanding. This will open Pandora's can, sort of, because really intelligent surveillance and ad targeting becomes possible. Combine a neural network and a lexicon and map an uttering to a graph with probabilities where the graph nodes are entries in the lexicon. Note that this is partly independent from speech recognition. Perhaps speech could be translated to a string of word alternatives with…

Can you give an example of something you want this system to understand?

A couples' reading list.

Step 1: My wife and I both download an app.

Step 2: We link our accounts.

Step 3: We each find and read articles in the app, Pocket-style.

When done with an article, swipe right if I think my wife should read it. Swipe left if I don't want to pass it on.

Step 4: Open the queue of articles that my wife thinks I should read. Read them. Swipe right if I want to chat about it with her. Swipe left if I don't.

Step 5: On the weekends, as we're going for our walk, talk about the articles we both found intellectually stimulating.

That's actually neat idea. I will probably build the first after I done completing my react native course.

The recent election should have made it clear to everyone that many communities, centered around industries like manufacturing or fossil fuel energy, have been decimated in the last few decades or so. These are obviously large trends, but in our technological and economic progress we should figure out how to make sure these communities are not left behind. I would like to see a larger effort for the SV community to e…

The disparity in technical knowledge is enormous along with the lack of optimisation by using humans instead of robots.

It's time to go to the next level, with universal income and less (much less) working hours, free education and so forth.

The alternative is dark ages + war.

I'm intrigued by the Futamura projections and the possibility of getting a compiler for a programming language "for free" by using partial evaluation to specialize an interpreter. It appears that fully automatic theorem proving technology isn't powerful enough for this to work well enough to be interesting.

But what about proof assistants? It struck me that using a proof assistant to guide the theorem prover inside a partial evaluator offers an opportunity to repartition the coding task. The idea of "end user programming" always fails because we cannot sufficiently separate the idea of a program that serves as specification (here is what we want done, its a shame that this specification isn't really runable because the implied algorithm is too inefficient (think about PROLOG, where a naive program may well be logically correct, but backtracks itself an exponential runtime)) and a program that describes a tolerably efficient algorithm. The poor end user has enough trouble with writing code that specifies the computation correctly without worrying about computer-sciencey stuff about how the computer should actually go about computing it.

If only there was some way the person rewriting the code to make it go fast could do so at one remove. He works with the end user programmer first time through, but subsequent revisions by the end user get rewritten automatically...

This was the vision I tried to articulate in https://groups.google.com/d/msg/comp.lang.lisp/5p8oVP5dGbU/V... but my health has failed and I've not got any further forward :-(

Earlier quoted context omitted.

Both ideas are personally music to my ears. I also happened to work on some of the titles you mention and a huge player of UO. What a game! On that thread, an arcade arena style PvP, where play is progressive and evolving. Basically LORD (legend of the red dragon) with today's VR tech. But Riot will undoubtedly see it and steal it though.

Nice to know I'm not alone! As for Riot, I don't think they would have eyes for anything other than MOBA.

nah, they're developing a game in the 1v1 fighting arena.
