Jon Callaghan, co-founder of True Ventures, believes smartphones won’t be central to our lives in five years — and may be irrelevant in ten. This isn’t speculation. It’s an active investment thesis shaped by two decades of backing companies that changed how humans interact with technology.

Callaghan argues that phones are a poor interface for intelligence: disruptive, inefficient, and ill-suited for how humans actually think and communicate. As AI accelerates, he sees the real bottleneck not as intelligence itself, but how we access it — opening the door for entirely new interaction models.
