Fridman: "When do you think SpaceX will land a human being on Mars?"

Musk: "Hm." (thinks ~20s) "Best case is about five years, worst case ten years."

Carbon Brief is now giving 4%.

(Yes, this means PredictIt is mispriced. I don't know if that's a big deal after fees, but I guess if you know people who are on PredictIt and allocate money effective-altruistically, please consider letting them know.)

If there's a human-level AI by 2075, it will probably have existed for decades, which means an intelligence explosion will probably have happened, which means a huge amount of optimization will have been poured into getting more intelligence out of less computing power. Current estimates here seem too high by a lot.

Berkeley Earth is giving 18% for 6th, 7th, or 8th place and 99% for 1st-8th place. 2021 is currently in 6th place, so this corresponds to an answer greater than 81%.

Based on [the data cited by Fruo](https://www.kansascityfed.org/publications/research/oke/articles/2016/economic-damage-large-earthquakes), no earthquake since 1985 technically counted as major. Loma Prieta and Northridge met the damage requirement, but at 6.9 and 6.7, they narrowly missed the magnitude requirement. Loma Prieta barely did enough damage, so let's say damage and magnitude were both coin flips and if we rerolled it we'd get a major earthquake 1/4 of the time. Northridge easily did enough damage but only came within 0.3 of the magnitude requ...

Scott is now "cautiously optimistic that the Times has changed their mind"

[Our World in Data](https://ourworldindata.org/) has a good graph of US hurricane landfalls through 2017. A quick look at Wikipedia suggests a Cat 2 and a Cat 4 for 2018, and just a Cat 1 for 2019 (so far, but we're far into the year and it won't mislead us too much to use that as the full count). Assume the number of US landfalling hurricanes in a year draws from the past 20 years, so 2/20 chance of 6, 2/20 chance of 3, 3/20 chance of 2. By my count, 13% of landfalling hurricanes since 2000 have been Cat 4+, but let's use 20% to be safe in view of recen...

According to Metaculus, the [75th percentile is 60M infections](https://www.metaculus.com/questions/3529/how-many-human-infections-of-the-2019-novel-coronavirus-covid-19-will-be-estimated-to-have-occurred-before-2021/). That's under 1% of the world population. Presumably the fraction among Metaculus users would be lower. Only some of the infected will have a doctor's note. There have been 36 predictions, so I'll wildly guess 20 predictors now and 50 predictors eventually. I'd guess fewer users would go to the trouble of posting their doctor's note by the...

It would be interesting to see a question of the form "will one of the following ten improbable events, each of which is too improbable to get its own question, happen this year?"

* civil war resulting from the 2020 elections * other unlikely wars (within EU, within NATO, US vs Mexico or Canada, US vs Russia or India or China in the next year) * unlikely technological breakthroughs (cold fusion, faster than light travel) * surprising but widely accepted scientific results (ESP, relativity disproved, life on Mars) * unlikely presidents (Oprah, The Rock, any Libertarian or Green Party candidate) * humans landing anywhere other than Earth/Moon/Mars, or anywhere other than Earth in the next year * average 2020 temperature at least hal...

The event in question has happened only once so far, which suggests "normally" the probability isn't much above 1% per year. That it happened in 2017 suggests this probability has been rising. But for the community's 68% in 4 years to be reasonable, it would have to have risen a lot. If I look at various other hurricane-related statistics, I see some support for increasing numbers of intense hurricanes, but I don't see any support for the kind of order-of-magnitude increases needed here. Ocean temperatures haven't made a sudden huge jump either. The "at ...

looks impossible at this point

@steven0461 Also more about gene editing and embryo selection.

I think this can resolve negatively based on the data here showing 0.89 for 2022 compared to 1.02 for 2020.

@olliebase22 It's hard for me to imagine an AI system capable of killing >10% of the population that isn't also capable of self-improving and self-replicating to the point of having a decisive strategic advantage over all human actors. (Not impossible, though. For example, maybe it doesn't take a superintelligence to hack nuclear weapons systems.)

98+% chance to be in the top 2 according to Berkeley Earth. 2019 is currently #2.

@ChrisCanal It wouldn't have counted because you joined after the question opened

What if, out of every 1000 civilizations, 999 stop being detectable after one century and 1 colonizes the universe and remains detectable for trillions of years? Taking the question literally, I don't see a plausible case for anything below the top end of the answer range, unless maybe it involves extremely convergent incentives to leave no trace or a relatively early end to the whole universe. (edit: it takes less than trillions of years for most galaxies to become unreachable, so there's that too; basically I think the question assumes a bad model and ...

The question text says:

This question will close retroactively to the resolution time.

The resolution time is still a few days away. So how come it's currently closed?

The [Met Office](https://twitter.com/metoffice/status/1473337473925148674) gives a central estimate of 1.09 degrees for 2022, the same as the anomaly for 2021 based on Jan-Sep, which I think may be a slight underestimate for the full year. So based only on this, the estimate would be 50% or a bit lower. > Met Office scientist, Dr Nick Dunstone said: “Global temperature has been slightly suppressed during 2021 because of the cooling influence of La Niña in the tropical Pacific. With another La Niña now underway, making this a so called ‘double-dip’ La Ni...
