Discontinuity in altitude records

Rockets may have caused a discontinuity in altitude of human projectiles. This investigation is not complete. Details We have collected some altitude records, shown in Figure 1. It looks as though rockets may have represented

2015 FLOPS prices

In April 2015, the lowest GFLOPS prices we could find were approximately $3/GFLOPS. However recent records of hardware performance from 2015 and earlier imply substantially lower prices, suggesting that something confusing has happened with these

Human-level hardware timeline

We estimate that ‘human-level hardware’— hardware able to perform as many computations per second as a human brain, at a similar cost to a human brain—has a 30% chance of having already occurred, a 45%

Accuracy of AI Predictions

Chance date bias

There is modest evidence that people consistently forecast events later when asked the probability that the event occurs by a certain year, rather than the year in which a certain probability of the event will

GoCAS talk on AI Impacts findings

Here is a video summary of some highlights from AI Impacts research over the past years, from the GoCAS Existential Risk workshop in Göteborg in September. Thanks to the folks there for recording it.

Recent trend in the cost of computing

The cheapest hardware prices (for single precision FLOPS/$) appear to be falling by around an order of magnitude every 10-16 years. This rate is slower than the trend of FLOPS/$ observed over the past quarter century,
