What are the key differences between ChatGPT, Claude, Gemini, Copilot, and other top AI tools? How deeply should you be concerned about AI systems using your personal data? Are the reported inaccuracies and biases of the AI platforms really as bad as what I read? Earlier this month, we asked you, WIRED subscribers, to send in your questions about generative artificial intelligence, and these are just some of the excellent queries we received. On Wednesday November 20, we hosted a live Q&A session with WIRED's Reece Rogers, the author of the "AI Unlocked" newsletter, the monthly AI ethics and advice column "The Prompt," and countless news and how-to articles about the impact AI is having on our lives.

Predictions of when machines will make us obsolete seem to come either from AI evangelists or doom-mongers with little practical experience of the field. Now though, researchers have carried out the largest-ever survey of machine learning experts on the subject. The advent of AI that can outperform humans at various tasks will have a dramatic impact on society, so forecasting when particular skills or jobs will be automated could be invaluable for policymakers. But the field is so fiendishly complex and has so many specialized sub-disciplines that there are very few people in a position to forecast when these breakthroughs will come. So instead, researchers at the Oxford University's Future of Humanity Institute decided to crowdsource the problem.
