And just how are compilers a business space in which innovation should take place? Most major compilers activity has long-since been displaced into open-source and academia.
Edit: Also, compilers to move code from mainframes to commodity servers, recompilers to switch architectures (e.g. Rosetta by Transitive), etc are big business. Are they going to make you a billionaire? Probably not. Can you make a couple million and a great ROI? Absolutely.
I speak with some fair knowledge of compilers, PLs, runtime systems, and OSs when I say: massive companies will also throw money at me if I can turn lead into gold.
A compiler cannot transform an inherently stateful, sequential program into an inherently parallel program that can be easily parallelized-the-hell-out-of. This is why there has been actual interest in shifting over to functional programming among those who need lots and lots of concurrency.
There do exist systems that will, for example, guarantee the determinism of threaded applications -- making them more predictable and debuggable. But DThreads still won't take a fold and turn it into a map.
Given enough time and memory more things are possible. Heck you could probably add speculative execution to many programs for more speedup. You are right in that the easy stuff has already been done, but that doesn't mean the hard stuff can't be done - just that it is hard. The good news is that people are prepared to pay for hard stuff.
2) You've gone into the research world, which concedes my original point about it not being a viable business ;-).
2) Not really. You've used current thinking to define your business model. Think disruptive instead. And worst case you'd end up spending Ycombinator money and end up with a better CV.
Some thoughts: It is possible now for a compiler to chew through terabytes of open source code to build up an information bank. Internal representation of code can be centrally submitted to see if anything matches and provides more compilation hints. Runtime profiling could submit back big O information. An organisation could run all the possibilities Seti-at-home style. ie rather than the compiler having to make more intelligent choices, it can just try all the choices.
To my knowledge, the middle step is actually the hardest. I'm no statistician, but do we have math/software that can look at a curve and distinguish a logarithmic function with little error in the data from a linear function with lots of error in the data?

The man-years here are the dominant cost. A SSC falls outside the start-up business model of releasing a "Minimum Viable Product" and all that jazz. You can't build a minimum SSC without building most of the whole thing.
That doesn't mean I wouldn't take someone's money to do it, but I'd be asking for a research-project budget, not an equity investment that has to be "ramen profitable".
Besides, I prefer home-made vegetable curry to ramen any day ;-).
You are still thinking "cathedral" as the project structure. I think "bazaar" is a better approach - try all the things, fling stuff against the wall and see what sticks. Use the terabytes of existing code to learn. I see the latter like spoken language translation. The approach used to be coming up with rules from experts which is very expensive. Nowadays they use statistical approaches which relies on having lots of data, uses humungous amounts of machine time to build the translation, but uses very few (expensive) people.
A YC startup doesn't have to be profitable or even come up with a MVP - it has to show there is merit to what they doing and some probability of success in the long run.
This means not having to guess big O correctly, or access patterns or other stuff in advance. It is possible to add future optimisations and not worry about current ones since they just won't be used work inapplicable workloads.
Then what's the point of a YC startup? Doesn't have to make a profit, doesn't have to build a product... basically, sounds like it doesn't have to build a company.
