That's why I said not now anyway. In the past, sure, it drove innovation to a great degree. But at this point we've wrung out the biggest gains. Almost anything NASA develops nowadays has little benefit to the public at large. It's entertainment mostly.

It can have huge consequences for us down the line. For example when Theodore Roosevelt decided to preserve national parks, it wasn't as big of a benefit to the public, mainly recreation. But in Yellowstone's hot springs a bacteria was discovered which now helps major biological processes through a technique called PCR.

Investments in science can have huge payoffs.

We should consider the alternatives. We're borrowing $trillions annually, so we have to pick our battles carefully. Why spend $billions to maybe possibly discover something like that, when the same $$$ can definitely pay back on some other crucial item? For example, most NASA funding should already have been diverted to solving the dead zone in the Gulf of Mexico; that's a more critical need that's currently being ignored. And that's only one of many giant cleanup tasks left to be done.
