Cuban framed the current moment as a trial-and-error phase, where people are testing what works and what doesn't."We're in that trial and error phase where people are like, 'We're going to try it, see what happens,'" he said, adding that response rates will likely fall as more AI-generated messages flood inboxes. "Then they'll get bored, and then it'll drop off," he added.
