We are as few as 20 years and $6 billion from reliable scramjets, Henry!

Isn't this pretty much true of any sort of ramjet
(i.e., not limited to the Bussard variety)?
I wouldn't be quite that harsh. For some not-too-demanding cases of

Now scramjets, yeah, they mostly work better as drag brakes than as
propulsion, so far. :-)
