A company called GRU Space publicly announced its intent to construct a series of increasingly sophisticated habitats on the Moon, culminating in a hotel inspired by the Palace of the Fine Arts in San Francisco.
On Monday, the company invited those interested in a berth to plunk down a deposit between $250,000 and $1 million, qualifying them for a spot on one of its early lunar surface missions in as little as six years from now.
Here is the full story, via the excellent Samir Varma.

Following up on my recent post, which suggested less skilled immigration into the UK has not been a disaster, the question has been raised about long-term negative political externalities. Will not migrants enter the country and make electoral outcomes worse? I would offer a few points in response:
1. If this is the argument, one needs to admit that immigration has gone well enough in the UK to date. This argument is about the future, not the past.
2. The UK has indeed had a variety of poor leaders as of late. It is very difficult to hold immigrants responsible for them, mostly it is the native white Brits who have been at fault. You might not like how UK Muslims have shaped some of the Middle Eastern statements of Labour, but that is hardly a relevant factor behind the slowdown of the British economy, or of British gridlock.
3. There is a very real risk that Reform will win the next election and then implement bad economics policies, above and beyond whatever you think of their approach to immigration. But if that is the real fear, it would be good to limit their popularity by talking up the positive side of immigration. I am not suggesting that any of us should tell anything less than the full truth, but obviously there are many positive aspects of migration that even professional economists can get wrong. Does immigration mean “higher home prices” or “capital gains for domestic homeowners”? Well, both, but you hear much more about the former than the latter (even Gemini got that one wrong). Let’s redress the balance, and lower the risk of future bad economic policy while we are at it.
4. Sometimes immigration weakens the demand for welfare state transfers, since the immigrants are viewed as outsiders. In Britain, that would currently be a positive at current margins. I recognize that is by no means the only political effect, but in any case do not assume that all of the political externalities are negative.
Above all else, it is difficult to paint immigrants as major villains for Britain’s troubles so far. Just read through the original analysis again. It has not been seriously countermanded, and do most of their problems are indeed the fault of the white people.
That all said, I would readily admit, and indeed stress, that a better set of migration policies could have put Britain in a much better position than it is today.

Here is but one part of the results:
Given complementarity between the two sectors, the marginal returns to intelligence saturate, no matter how fast AI scales. Because the price of AI capital is falling much faster than that of physical capital, intelligence tasks are automated first, pushing human labor toward the physical sector. The impact of automation on wages is theoretically ambiguous and can be non-monotonic in the degree of automation. A necessary condition for automation to decrease wages is that the share of employment in the intelligence sector decreases; this condition is not sufficient because automation can raise output enough to offset negative reallocation effects. In our baseline simulation, wages increase and then decrease with automation.
That is from Konrad Kording and Ioana Elena Marinescu of the University of Pennsylvania. I am very glad to see ongoing progress in this area. Via the excellent Kevin Lewis.

Social Security also got quietly more generous during this period. Each year, the Social Security Administration compares the C.P.I.-W (the Consumer Price Index for Urban Wage Earners) for the third quarter to the third quarter of the previous year and, if needed, adjusts benefits upward to compensate for inflation. There happen to have been three years during Obama’s presidency — 2009, 2010, and 2015 — when the mathematically correct cost-of-living adjustment would have been negative. What actually happens in this case is that seniors get zero cost-of-living adjustment, which means that, in real terms, benefits ratcheted upward.
Then during the Biden administration, Congress ended up passing the Social Security Fairness Act, which increased Social Security benefits for a disproportionately affluent set of retirees with access to other pensions with very little fanfare. This happened via a hugely bipartisan vote, so even organizations that were critical of the idea when it was first proposed were mostly silent as it actually happened. Then during the 2024 presidential campaign, Donald Trump proposed “no tax on Social Security,” which is really just a way of making Social Security benefits mildly more generous for high-income seniors.
That is from Matt Yglesias. It would be amazing if we got away with all of this!
