There have recently been lots of discussions about the risks of AI, whether in the short term with existing methods or in the longer term with advances we can anticipate. I have been very vocal about the importance of accelerating regulation, both nationally and internationally, which I think could help us mitigate issues of discrimination, bias, fake news, disinformation, etc. Other anticipated negative outcomes like shocks to job markets require changes in the social safety net and education system.
