Coal-powered steam turbine is not that more efficient than a portable gas generator so considering coal is more carbon-intensive it's actually about the same or even worse in terms of emissions if you consider coal burning also produces mercury. Now nat gas-powered CCGT - different story. Good news is NYC is mostly powered by the latter and there's zero coal.
Weirdly (well not for me it's a charter metal festival cruise) I am too and interested in doing the same. Typically we use Uber and it's been a not great experience.
I would say it's often because people see individual examples in action. Some people follow those examples. Then more do. You are more influential than you think.
Depends on the shareholder. At Sergey Brin's level, that shareholder value shapes the future of humanity, a legacy affecting many more people and will last far longer than spending time with single, or even double digit number of children.
I can't really tell what you're trying to say, do you really think the shareholder value of Google is positively aligned with the future of humanity?
As in: If Google builds a really good AI and makes a lot of money from that, this will be a net positive for the world?
Sure, all lethal weapons are a horrific nightmare on some level.
But you also have to keep in mind that China, Russia and Hamas will gladly develop them anyway. Until we've figured out the worldwide peace thing, we need to keep running the race, awful as it is.
But AI weapons aren't horrific in some way common to "all lethal weapons." They have that and more.
AI weapons are specially horrific in the way they have potential put massive and specific lethal power under the total control of a small number of people, in a way (like all AI) that basically cuts most of humanity out of the future (or at the very least puts them under a boot where no escape is imaginable).
In some ways, they're even worse than nuclear weapons. A nuclear attack is an event, and if you survive there's some chance of escape. Station 100,000 fully automated drones around a city with orders to kill anything that moves, and the entire population will be dead in a couple months (anyone who tries to escape = dead, everyone else sees that and stays inside out of fear until they starve).
Manpower and attention limitations have been and important (and sometimes only) limit on the worst of humanity, and AI is poised to remove those limitations.
Honestly, I think the tech is probably getting pretty close to what I described. You don't need AGI or anything like it. Just autonomous surveillance drones watching for movement, and attack drones that can autonomously navigate to the area and hit the target (the latter is just stringing together a lot of drone tech I've seen implemented, e.g. https://www.youtube.com/watch?v=QzWIYOOKItM, https://www.nytimes.com/2025/12/31/magazine/ukraine-ai-drone...).
> But even if it's true, I don't see why letting China and Russia etc be the only ones having these weapons is good?
That doesn't mean the tech isn't scary (a bad thing) or that I want SV people like Schmidt developing it. There's something weirdly misanthropic and unhinged about many in SV.
He was responsible for a bunch of the anticompetitive hiring agreements with Jobs at Apple and he’s a fairly well known lothario, but otherwise benign IMO considering his competition at that wealth level.
He is also the man who said ”If you have something that you don't want anyone to know, maybe you shouldn't be doing it in the first place.” as if people are not being hunted for being LGBTQ even in the west, or persecutions of various kinds are a thing of the past, or spousal abuse doesn’t matter.
Hehe, my wife is from there, for the first few years she lived in Orlando I would crack jokes about how bad it is down there, noticed she was getting offended so I pulled back, but the last three times we've gone down there she swears up and down Miami drivers are the worst. Of course Orlando has I-4 as well, which is, its own special place.
1. The in-flight time from LA to Dubai is not 24 hours. A direct flight between the two cities is more like 15. If he was on a "24 hour flight", it was a flight with a stopover, which just goes to show the point about air travel time being bloated by non-flight time.
2. Concorde rather infamously could barely make the transatlantic trip from New York to London, because supersonic flight is expensive. Boom's currently nonexistent aircraft is planned to have about the same range. Neither could make the flight from LA to Dubai, which is a distance close to double their maximum ranges.
RE 1. - the example still stands. Travel time is best understood as falling into buckets. Roughly:
- < 1h - can go there for lunch, or as part of running some errands;
- 2-3 hours - can fly over, have a full day of work at remote location (or sight-seeing), and get back home for supper;
- 4-8 hours - can fly over, do something useful, fly back overnight or next morning;
- > 8 hours - definitely a multi-day trip.
(There are more buckets still, if you consider long-distance travel by sea or land, and then more when considering how people perceived travel in historical times.)
As long as the travel time stays in the same bucket, reducing (or increasing) it doesn't matter much to the travelers. However, going up or down a bucket is a huge qualitative change, and one people - especially the business travelers - are more than happy to pay premium for.
So back to our supersonic planes, cutting down the LA-Seattle travel time from 3 hours to 1.5 hours (and accounting for airport overhead), doesn't affect the kind of trips people take. Cutting down travel from LA to Dubai from your 15 hours to 5 hours means it suddenly makes sense for corporate executives to fly over in person for single-day meetings, where previously it wouldn't.
This is also why it's the business customers that are always the target for such ideas - regular people are much more price sensitive than corporations, and are fine with long and hard flights if it means they can afford them. Meanwhile, paying an extra $10k to get the executive on an important meeting might actually be worth it for a large company.
Even with airport overhead, there's plenty of routes a supersonic plane could drop from 4-8h bucket to 2-3h bucket, and that is still something business flyers would pay for.
Like which ones? Bear in mind that despite carefully worded PR, Boom has very much not somehow surmounted the laws of physics to eliminate the sonic boom that caused the Mach 2+ Concorde to be banned from going supersonic over land.
See the pesky thing is that if you actually read the paper you've been linking as opposed to just running with "NASA said it's possible", you'll notice that like I alluded to, at Mach 1.3 (theoretically!) "boomless flight" is much slower than Concorde's Mach 2+ cruise that the company certainly wants you to think of when you do your back-of-the-napkin supersonic flight time savings maths. And that's on top of requiring optimal atmospheric conditions, so not even a guarantee to begin with.
The laws of physics funnily enough are not something you can "move fast and break" or PR-speak your way around.
And NY to London really isn't bad. I have to do Zero Dark Thirty for London flights with a change in Newark but EWR-LHR itself isn't really much different from when I fly from BOS to SFO.
At a minimum, I'd want to be able to fly from the East Coast to continental Europe to avoid a red-eye but the biggest win would be trans-Pacific.
Yeah, in my opinion the point that "wouldn't it be nice if this was faster?" becomes a real issue is the point that you would feasibly need to get your day's sleep en route with today's airliners, because it's difficult to sleep for more than a few hours at a stretch on a flight even with business class conveniences (and that's before getting into the degraded quality of sleep). If I could catch a flight that's fast enough to let me hold off on sleep altogether until I get to my destination, then that's worth paying a premium even for economy seats. Unfortunately, that's also the point that a supersonic airliner becomes unworkable for airlines, because the fuel-to-passenger ratio just stops making sense. You can try to make it work with refuelling stops along the way, but that really eats up the theoretical time savings and adds its own operational overhead too.
I think we need an energy breakthrough with a denser and still cost-effective fuel before really getting into the era of supersonic transport. Maybe at some point someone will dust off the nuclear-powered aircraft designs of yore...
“ Blake’s pitch to airlines is enticing: “You’re already flying this route with a 300-seat plane where 80+ people in business class generate most of your profit. Give those passengers a supersonic plane, cut the flight time in half, and charge the same price.”
The math doesn't scan out on that, it sounds good for pitches and articles but is kind of nonsense once you think about it imo. It's going to cost way more than just 2x to run the supersonic jet along the same route per flight just in fuel and maintenance and you're cutting out all the low fare passengers they cram in the back so they need to make up even more money than just the fuel costs and running additional flights per day doesn't address the issue because the cost per trip is increasing so running more trips just keeps incurring those same costs.
It won't change the economics of the current class of aircraft. They will still need to have business class seats to pay for the economy cabin.
You will probably end up with 5 or 6 tiers of service instead:
Supersonic: Business + First
Subsonic: Economy + Eco+ + Business + First
Supersonic First will be a Veblen good that has a high price floor (like $30k). Business for time sensitive business passengers, and it's actually an Economy Plus seat for ~$15k.
It's very hard to resist marketing some service differences, particularly when you have two classes of users with different needs (speed vs. prestige).
The pitch quoted from the post I was responding to essentially said it was going to siphon all the business class fliers from normal flights: "Give those passengers a supersonic plane, cut the flight time in half, and charge the same price." There's no way businesss travellers would choose subsonic travel if supersonice was the same price for half the time.
We agree I think that there wouldn't be a similar price between the sub and supersonic travel options. The economics of running the routes can't work out to a similar price to existing offerings.
Estimate 4k for one-way biz ticket and 500 for economy, then that's about 240k from the front and 145k from the back. Actually, I'd expect them to optimize based on space, so if 40% of the plane is biz, then 40% of revenue should come from biz. Perhaps the most profitable routes with this config are 60% revenue from biz; other routes might be more like 2.5k-3k one-way biz.
But biz will be half empty or more at full price, so it gets filled with upgrades of coach tickets to reward frequent fliers or full-fare users. The average has to be lower. The biz price may also be optimistic. United EWR-LHR is more like your $2.5k-$3k. Delta has an ATL-LHR option for first/business class with a bed that's more like $8k-$10k, and their Premium Select, which is more like United's business class, is $2.5k. Interestingly, they offer more beds than big seats.
I remember pricing out the Concorde years ago, before it was grounded. BA's first class subsonic was $8k, Concorde was $12k. (2001 dollars) If you're paying those rates anyway, it might be worth it to go faster, if you don't mind the relatively small seat and limited food service. Coach was $400-$600.
