I know I saw this and told myself was going to reply, but I guess I forgot.
Disclaimer: I come from a philosophy background.
My biggest problem with computer science/mathematics/cybernetics people is that they often presuppose a scientism that is void of actual philosophical reflection. In the case of this Bach guy, he's reducing most of Wittgenstein down to the problem of communication. While it's true LW was in part trying to communicate, he was also interested in other problems. Turing similarly was interested in more than just communication. His historical analysis seems a bit revisionist, in this sense.
Another problem is the project of building a mind. He's approaching the project from a computationalist/constructivist pov. While I think it's cool he's going against the vogue (i.e. the connectionist paradigm ala Machine Learning), he's simply presupposing that these perspectives in philosophy of mind accurately represent what the human mind is.
From the pov of Philosophy of science (which could be called into question) this could be characterized as pseudoscience. He's not actively attempting to disprove any hypotheses, or forwarding any new conjectures. If we wanted to say he's just an engineer, and avoid the bags of the term "scientist", then more power to him. But often people in his position insist that they're scientists by virtue of the fact that they use math to describe things.
This isn't necessarily an attack on him individually, all I'm saying is that there's gotta be more standards in regards to what we call "science". I think his project is mislead. I don't think you can brute force reality.
Hell yeah, thanks for the reply!
Just on a jumping off point how much would you say you watched?
Because I know Joscha is very much against scientism, and I should have clarified better. I bet he would call himself an engineer and not a scientist because he left teaching at Harvard.
"Scientists" to me are more weirdos who have a hard time accepting the "status Quo" and they have a hard time reaching consensus, so anytime you see a bunch all on the same page there must be something going on behind the scenes. Being a "Scientist" isnt a "career" like the West currently wants it to be. You only need a few to make society work, not the droves and droves of them we create at universities. More Plumbers, Electricians, Engineers, Doctors. Less Meta Physics, Philosophy, Theology, Psychology
I would agree that the problem is greater than communication, but we arent going to get anywhere while we still use broken languages (semantic, symbolic, math, etc.)
Computation is a domain of math which gits rid of nasty things like infinites (which dont work as proven by Kurt Gödel)
I see Joscha as someone seeking to clean up our communication before we can make anymore progress.
He isnt looking to posit beliefs or rigorously disprove standing hypothesis which is what Philosophy is about in my limited understanding (sorry I didnt quite stick to the thread theme of strictly "Philosophers")
These messy infinities has lead us to retarded dead ends like String Theory and rampant Mysterianism (the belief that the human mind could never comprehend itself)
I hope my points were lucid enough that you can tear them apart so I can go find better ones
