I have something somewhat similar at <https://blog.sentinel-team.org/>, tracking events that could kill over a million people.

> such a high price

For the target audience this is about 5-10% of a month's income, and so is more like a reasonable optimization.

> to meet me

To improve the distribution of dates, which is more valuable than any single one.

Perhaps look into Shapley values as well?

I think it's a good argument to say that we don't know for sure. But people who are addicted to youtube today would probably have done something more meaningful in the 1990s, 2000s, 2010s...?

We speak with Ivan Vendrov about recommender systems and their impact on human attention and society & how these algorithms shape billions of hours of human time daily.

Good point!

I did briefly look into how much the estimated $7B was as a proportion of GDP: 7B/2T = 0.35% of GDP, which feels like a lot. For 41 planes it'd be $170M per plane, which seems reasonable when compared to US bombers, but unclear for Russian ones, but my guess is it's not too far off. This source (https://www.france24.com/en/europe/20250601-ukraine-says-it-...) says $2B for the planes alone, but then you also had the airbases &c, and maybe a submarine base <https://newsukraine.rbc.ua/news/major-explosion-hits-russian...>. I'd still expect it to be a bit exaggerated for propaganda effects, but it does seem reasonable all in all.

This is a weekly brief looking at what the most important risks and precursors of global catastrophic risks are each week. To do this, we parse millions of news pieces a week and discuss the most urgent ones with elite forecasters to find out.

That seems like the kind of problem that would be easily done through monte-carlo approximation? How hard is it to get 1M random rows in a postgres database?

> Can a board member be reasonably responsible for the actions of tens of thousands of employees if they have not explicitly enabled or condoned criminal behaviour?

Not sure what the answer is, but if the answer is yes, then that incentivizes them to build the oversight and reporting capabilities to be able to steer away from crime, and to hire noncriminal subordinates &c.

One way this could look in practice is board members having to post a large bond that gets taken away if the commpany is found to commit crimes during their tenure.

Anecdotically, the Real Madrid requires a large bond (57M) posted by the president. http://news.bbc.co.uk/sport1/hi/football/europe/8076515.stm

> Any event or series of events that removes mankind's ability to produce modern computers is a global extinction-level event and rather than dicking around with computers one should really be considering suicide to avoid a slow, painful, inevitable death in a hostile world surrounded by misery.

To give some color, here: https://blog.sentinel-team.org/p/how-likely-are-various-prec... is a list of a few things that could kill over 1M people in one year. Maybe your statement is not the case for solar storms in particular.
