This is like saying thread count is always the bottle neck in computation. More money allows more parallelism as you can pay for more people and more equipment for more research. As in computing, there are diminishing marginal returns and surely a version of Amdahl's Law for human endeavors.

The softer the bed linen, the more rested the computer scientists will be and the more likely they are to come up with novel solutions that lead to faster computing.
