Or worse, pursuing something already proven not to work.

Or worse, pursuing something already proven not to work.
- porkbrain 2y agoViewed through the lens of personal development I suppose one could make an argument that there wasn't much difference between rediscovering an existing valid or invalid solution. Both lead to internalisation of a domain's constraints.
- somenameforme 2y agoThe problem is that when the proof is wrong, as in this case a related conjecture held up for 40 years, which is not a "proof" per se, but still ostensibly an extremely high reliability indicator of correctness. Another example is when SpaceX was first experimenting with reusable self landing rockets. They were being actively mocked by Tory Bruno, who was the head of ULA (basically an anti-competitive shell-but-not-really-corp merger between Lockheed and Boeing), claiming essentially stuff along the lines of 'We've of course already thoroughly researched and experimented with these ideas years ago. The economics just don't work at all. Have fun learning we already did!' Given that ULA made no efforts to compete with what SpaceX was doing it's likely that they did genuinely believe what they were saying. And that's a company with roots going all the way back to the Apollo program, with billions of dollars in revenue, and a massive number of aerospace engineers working for them. And the guy going against them was 'Silicon Valley guy with no aerospace experience who made some money selling a payment processing tool.' Yet somehow he knew better.
- necovek 2y agoAll the cases you bring up are not "proofs": a conjecture is very much not one, it's just that nobody bothered to refute this particular one even if there were results proving it isn't (cited in the paper). Similarly, ULA had no "proof" that this would be economically infeasible: Musk pioneered using agile ship-and-fail-fast for rocket development which mostly contradicted common knowledge that in projects like these your first attempt should be a success. Like with software, this actually sped things up and delivered better, cheaper results.
- vkou 2y agoAlso, SpaceX was exactly one failed launch (with every prior one being a failure) from bankruptcy. Had that one also been a failure, he wouldn't be running the US government and we'd all be talking about how obviously stupid reusable rockets were.
- necovek 2y agoHad they received the same grant money as Boeing ($4.2b vs $2.6b), it wouldn't have been such a close call. I'd also note that they were also late by 3 years or so: this did not produce miracles, it was just much cheaper and better in the end than what Boeing is still trying to do.
- Manabu-eo 2y agoHe is talking about Falcon 1, not CCDev. There was no close call at CCDev, nor any grant money for Falcon 1.
- necovek 2y agoThanks for the correction/clarification. Still, I would be surprised if SpaceX did not greatly benefit from knowledge gained in Falcon 1 development when building their Falcon 9 rocket and then optimizing it for reusability — they started development of Falcon 9 while Falcon 1 was still operating.
- NateEag 2y agoThis illustrates beautifully how stupid labeling ideas stupid is. To know that that an idea or approach is fundamentally stupid and unsalvageable requires a grasp of the world that humans may simply not have access to. It seems unthinkably rare to me.
- WalterBright 2y agoOn the other hand, I knew from the beginning that the Space Shuttle design was ungainly, looking like a committee designed it, and unfortunately I was right. (Having a wing, empennage and landing gear greatly increased the weight. The only thing that really needs to be returned from space are the astronauts.)
- scheme271 2y agoDo we know that the economics work for SpaceX? It's a private company and it's financials aren't public knowledge, it could be burning investor money? E.g. Uber was losing around 4B/yr give or take for a very long time.
- withinboredom 2y agoMost of their income comes from government subsidies and grants. So, it is rather funny to see the owner of the company running around the government and "cutting" costs.
- somenameforme 2y agoSpaceX's total funding from government grants and subsidies is effectively $0. They do sell commercial services to the government and bid on competitive commercial contracts, but those are neither grants nor subsidies.
- withinboredom 2y agoUmmm... you know the government granted them a bunch of money to go to the moon, right?
- somenameforme 2y agoNo, they didn't. The government wants to get to the Moon via the Artemis program (which will never go anywhere, but that's a different topic) and so NASA solicited proposals and bids for a 'human landing system' [1] for the Moon. SpaceX, Blue Origin, and Dynetics all submitted bids and proposals. SpaceX won. Amusingly enough Blue Origin then sued over losing, and also lost that. They were probably hoping for something similar to what happened with Commercial Crew (NASA's soliciting bids from companies to get astronauts to the ISS). There NASA also selected SpaceX, but Boeing whined to Congress and managed to get them to force NASA to not only also pick Boeing, but to pay Boeing's dramatically larger bid price. SpaceX has since not only sent dozens of astronauts to the ISS without flaw, but is now also being scheduled to go rescue the two guinea pigs sent on Boeing hardware. They ended up stranded on the ISS for months after Boeing's craft was deemed too dangerous for them to return to Earth in.

- ExoticPearTree 2y agoI think Musk had a better imagination and the money to fund that imagination without constraints or internal politics.
- phyzix5761 2y agoThat's how the best discoveries are made.
- Manabu-eo 2y agoOr how a lot of time is wasted. For example on perpetual motion machines and infinite data compression.
- phyzix5761 2y agoA lot of major scientific discoveries were made while people were trying to turn base metals into gold; also known as alchemy. Some examples include discovering phosphorus, the identification of arsenic, antimony, and bismuth as elements rather than compounds, and the development of nitric acid, sulfuric acid, and hydrochloric acid. Alchemy ultimately evolved into modern chemistry. I think the key is that thinking that something is a waste of time is the type of mentality that prevents individuals from pursuing their interests to the point where they actually make important discoveries or make great inventions. If you put enough time and energy into anything you're bound to learn a lot and gain valuable insights at the very least.
- SkyBelow 2y agoOutside of math and computational science, nothing is proven to not work because scientific research doesn't work in proofs. Even in math and computational science, there are fields dedicated to researching known proven wrong logic because sometimes there are interesting findings, like hypercomputation.
