Hey this guy has automated Wikipedia!
Now which needs does this fulfill is another problem...
On a more serious note, this, erm, "NKS" is not really new, it's been used for ages. Modelisation has been the base of science since long before it was even called science (one could argue that drawing hunting scenes on cave walls was already a kind of modelisation. Religion is a kind of modelisation too). Throwing a metric shitload of computing power at it only moderately helps because it won't solve any problem unless you fully know all the parameters involved, and when you're at that point, you basically already answered the question. Having the machine understand the problem is the least of your concerns: 2 days studying your computing language of choice, sorted (or you can hire a Machine Whisperer).
Natural language for machines might be a good thing (think domotique for example), but it has only very limited applications in science. It's even counter-productive, as scientists love nothing more than being cryptic. And studying simple fairytale models (like the game of life) won't lead you anywhere scientifically speaking because these "models" have no factual basis. Given 1+1=3, you can prove that 1+1+1+1=6 (if you assume that 3+3=6 of course) but it won't bring you anywhere in real life.
It's basically the same problem as with climate simulation. Lots of models, none agreeing with the others, and none able to reproduce real life evolution (well, all the ones old enough to be confronted with real data failed, at least). That's because we still fail to grasp all the parameters involved.
If a supercomputer is able to understand natural language and can aggregate and parse all knowledge, it will merely allow the layman to get already-known facts or beliefs. It cannot lead to any genuine discovery. Automated Wikipedia, really. Or a dumbed down automated scientist (scientists are raised to do precisely that, plus hopefully some "out of the box" thinking -though that last part tends to disappear. I should know...).
Now I guess the real questions are: will this new-fangled system be cheaper or more expensive than training a flesh-and-bones scientist? And will it be able to sustain itself and produce new useful knowledge in the absence of scientists? If answer to both question is yes then YAY! Retirement time!
My belief however is that it would be cheaper and more efficient to get scientists to speak natural language... probably a bit more difficult though.
Mine is the white cotton one with the pens and timer in the chest pochet, thanks.
TL;DR: I was bored.
