I hadn't made that connection but it's really apt. People watching Falcon 1 flight 4 get to orbit probably said "It's 165 kg payload, so what? We've been sending satellites to orbit for 50 years. ULA just sent (https://nextspaceflight.com/launches/details/1538) a 2000 kg payload to orbit 3 weeks ago!" It really is significant what Boom did in the time frame and budget they had.
