As we embed AI agents into our lives and workflows, we’re learning the (sometimes surprising) ways in which they outperform human beings, and other ways in which they fall short.

It’s well known that people are not particularly adept at spotting phishing scams; 1Password’s research found that 61% of Americans have fallen v
