ALEX KARP SAYS THE BIGGEST MISTAKE HE SEES PEOPLE MAKE IS LEAVING SOMETHING THAT WORKS TO CHASE SOMETHING NEW He was asked what he and Peter Thiel would start if they were 25 today. "A mistake I've seen people make over and over is you assume the best thing is the new thing, when in fact maybe the thing you know could be 10 times bigger." "In my experience, you want to hang on for dear life to the thing you have that's working. That is actually my real answer." "Answers that are true are often not persuasive." He said Thiel was right about one thing above all the others. "Picking me. I might not have picked me." He also said the way the two of them argue is baked into Palantir $PLTR. "You can't just make a superficial argument and think that's going to fly in any way. The rigor of the argument would matter as much as who's right or wrong."
