At just after the 40 min mark, Larry Ellison talks about passwords going away in Oracle and ransomware. I use Oracle all the time. They have no technology that replaces passwords. Their support site just offered 2FA this year. They patch their software quarterly so a hacker has at least 90 days to exploit vulnerabilities for ransomware attacks. Oracle is a massive slow moving business.
If we need a password-less world and should be worried about ransomeware then why would we want our data to be centralized? This would allow it to be stolen and used against us.
