WhiteFiber (WYFI) CEO Sam Tabar says the demand for A.I. buildout is "very real," adding that the A.I. stock sell-offs are far overdone. He attributes the slowdown to a struggle to find power, a headwind he sees persisting for data centers. Sam also explains WhiteFiber's role in the A.I. buildout and the company's long-standing relationship with Nvidia (NVDA).
