Yes, if your fuel tank ruptures, you lose the vehicle. Just like every other rocket ever built. With the possible exception of the Saturn IB, no NASA rocket has had what you might call "fuel redundancy" and even the IB used a common central oxidizer tank. Again, that the Falcon 9 has had failures and still made it to orbit, is unambiguous proof that it does contain some redundancies. That NASA has certified Dragon as fit for crewed flight, means they two are satisfied with the redundancies of the design.

That the Falcon 9 has engine out capability (which it has successfully demonstrated) shows your statement to be false. As well, for crew, you are using Dragon which has it's own set of systems for protecting it's occupants in the event of an issue

Shh, don't even start to tell people about DTaP. If you're 50, you've likely had it 10 times

The vast majority of vaccines aren't a single dose fix. Why should this one be any different

5 of the top 10 pharmaceutical companies are European (only 4 are US based)

The Taxi lobby pushed hard to ensure the Monorail never went anywhere near the airport

Scarcity has zero to do with backing. The whole reason that the world moved off the gold standard is that linking economic growth to our ability to dig shiny metal out of the ground was dumb

Starlink sats are about 200km lower than Iridium, the newest ones will also use direct links between sats, both of these reduce latency. The biggest reason for Iridium's initial failure was the high capital cost, which led to high service costs.

Itt's more that you wreak havoc on the cell networks beneath you as you hand off from site to site to site at 900 km/hr. It generates a lot of extra traffic on the network

Geothermal has it's own issues (unless you're someplace like Iceland or Hawii). You either go with closed loop which in most places means you're extracting energy from the ground faster than it is replenished. Or you go open loop and your bringing large amounts of dissolved heavy metals to the surface, creating another waste issue

I think it;s more that tools like Facebook are a symptom of the problem, and that is our ability to receive an entirely curated information bubble and community that aligns precisely with our pre-ingrained biases. If you don't believe in climate change (or do believe in climate change) you're likely to be presented with media (be it TV, social media, or newsfeeds) that largely reinforces your perspective, you can connect with people around the globe that believe as you do. As a result we become increasingly entrenched in our positions.

The RFP said "up to 2 contractors"

Yes it does predate Nazism, that doesn't change the fact that is was a core ideological principle of theirs. Hilter devoted a whole chapter to it in Mein Kanpf and was going to devote a fair bit of his planned "sequel" to it. The invasion of the USSR wasn't some last minute idea after the fall of France, rather it was the ultimate endgame from the very start. It was the invasion of France and the war with the UK which was more unplanned (and in the case of France, a happy accident)

The cost of fuel for a Falcon 9 is only several hundred thousand dollars. A drop in the bucket compared to the hardware
