AI agents seem to be killing the ability to do cold outreach. Look at it from my perspective — someone who gets dozens of unsolicited invitations/requests in my email from strangers every day. In the past there used to be a sharp distinction between unpersonalized mass emails and those that were meant specifically for me. My spam filter could mostly automate this classification, and it even when it didn't, it would take me only a few seconds to tell if an email was worth reading/responding to. Now the distinction is gone because it is trivial to use AI to send out mass emails that appear deeply knowledgeable about each recipient's work and expertise. I guess we have to go back to the bad old days of needing to be "introduced" to someone before communicating with them.
