Comment by Eddy Keming Chen

Now, I believe we have already reached artificial general intelligence (sometimes called human-level machine intelligence): we have created AI whose intelligence is general in the way human intelligence is, broad enough to span many kinds of problems, from mathematics and science to language and everyday practical reasoning, and deep enough to handle them well. [...] When we wrote our Nature Comment in Feb. 2026, I thought superintelligence might still be five years away. Recent developments have changed my assessment. I now believe we may reach this reality sooner than anticipated, perhaps even within a year.
