This is really creepy / nauseating to me, and also creates a high value target at World. You can reset leaked passwords, but you cannot reset your retina. If you choose to believe 100% in this service and willfully ignore implementing patterns to combat social engineering this could end up worse. From what I can gather (from Gemini), deepfakes take advantage of organizational social pressure, like a CEO demanding something instantaneously, or hackers being inside your email system for a long time. Perhaps this could be short-circuited by an organization actually requiring people to always call back officials on a secure phone number, confirm with shared personal knowledge, and never respond to a demand without out of band verification. I also wonder what if Zoom just calls the participants in such high-stakes meetings, instead of allowing participants to click on a link they trust because someone emailed it to them. Then the corporate security office can just verify the Zoom server. And iPhone/Macbook already have biometric sensors too but have Secure Enclave.. yes there is a big value in being able to identify someone for sure but putting it all in a single company's hands sounds like waiting for them to be attacked.
