This flash presentation has been circling the net for quite a while. To be blunt, it is complete nonsense, as it is nothing more than the creator's personal ideas, which don't seem to be based on anything.
Anyway before I proceed I'll say that String Theory is the one area of physics I know nothing about aside from a collection of factoids regarding its differences from "Standard" Theory.
From what I gathered, although it offers explanations about our universe and makes sense mathematically, it is not testable and unobservable with out technology.
I don't think the full Stringy regime is testable, that is we can't reach the energy scales where String Physics becomes dominant. However, to my understanding, there are a lot of efforts on what is called String Phenomenology. This is an attempt to see what String Theory predicts when we reduce it to energy scales which can be probed at the LHC and possible differences between it and the Standard Model at those scales.
There is also String Cosmology which attempts to find differences String Theory introduces into the large scale structure of the universe.
I'm not really sure what to think now. Is string theory at all feasible? Is it something that has any weight or is it completely disregarded at this point in time.
One statistic is that citations of String related papers have dropped a good bit in the last year. This could be just a temporary lull in interest though.
