I feel like this assertion deserves a big "maybe" in there somewhere.
For the record, I hope Boom succeeds. When I was a kid I learned about the Concorde as the future and it's been a real shame to watch it stay in the past.
I’d like to see the trajectory that takes you from NY to London in 19 minutes without squashing you and/or causing insane amount of heating. Bonus points if the only source of thrust is a fancy air brake.
One past example of predicting the future with unlimited budgets is the xerox alto.
The Lofstrom Loop is possible today for a few billion dollars. Though "catching" an incoming capsule with a Loop is going to take a while to human-certify.
I used to imagine the same thing when I was a kid, that by the turn of the millenium we'll be piloting flying cars. But here we are in 2018 sitting in traffic jams in the same old boring four wherlers. Yes they're more efficient and reliable but still a chariot on wheels.
Nowadays I'd rather imagine supersonic flight is possible from an economic standpoint and wish Boom the best of luck with their enterprise.
Except in genetic, chemistry and computer sciences, most other fields looks a lot like where they were 50 years ago.
It's true that there were a lot of incremental changes, greatly improving the overall efficiency, and also a far wider adoptions of these technologies. But the basis for most concepts/designs are in fact quite old.
The first computers are from the 50ies and the transistor from 1947, the 737 first flew in 1968, the 747 a few years later, the first nuclear plant dates back from 1956, Soyuz still flies despite being based on the 1957 R7 ICBM, the basic design of cars is pretty much established since the 20ies or 30ies.
Short of the internet (agree it's a big "short of"), our lives are not that much different than in the 70ies or 80ies (at least in the US/Europe).
And in fact, it's not a big surprise. A big factor in radically changing our material condition is to get energy, and a lot of it. First there was coal 200 years ago, then oil and gaz in the late XIXe century (plus electricity for its versatility and ease of distribution) and, finally, nuclear fission (and it was only a semi-success seeing the current and near future adoption). Short of a new energy source, with an output an order of magnitude higher than we currently have (Fusion? if we manage to pull it of), I don't see why we will have major technological changes.
But sometimes several things come together to lead to a new capabilty. SpaceX recoverable rockets aren't just due to incremental improvements in rocket engines, they're due to improvements in a whole host of different areas - materials technology for lighter rockets, software improvements, better heat shielding materials and frankly new economic imperatives. Those all came together to push us over the edge of a new capability. Maybe the same will happen with supersonic passenger planes.

I fly to Europe constantly on first class and tickets are usually circa $8,000 round trip. When I saw your "plane" with huge seat space, huge windows and $3,500 per round trip NYC-LON I immediately looked for your phone number to send you $350,000 for my next 10 years of flying. Please just take my money!!
Bottom line it will not be sustained so some deep alteration will have to be done. I would rather spend $8,000 in first class 7 hours flight this summer, than book my 3.5hr flight with you that will happen in 2028, because you are highly overbooked. Of course adding 100x more units in flight won't cut; air space is not like bakery you just can add another oven.
> We think there's a roadmap to making supersonic flight cheaper than subsonic flight is today. It will take a few decades, but that is absolutely the path that Boom is on.
In few decades we will be catapulted into space from London without engines on "the Moon elevator" and then pull back with Earth gravity, slowed down by huge magnets and safely land in New York in less than 19 minutes, door to door. Your approach is similar to those who envisioned building harness for 100 horses in a row to go faster, right before a Diesel engine was invented.
