I'd argue that there are some conditional factors here and they largely revolve around human capital. In fields with a very small number of people with prior experience, throwing money at the problem won't necessarily accelerate the path as fast as one where there are a large number of qualified people to tackle the problem. This said, continuing to throw money at a problem such that it leads to more and more people developing a skill set in the space would overtime help, but then again, they could reduce the amount of investment down the line, and you'd still have people who were highly specialized in said domain to target that problem anyways (abet being paid less).
