"A.I. is happening rapidly, and we didn't help people cope with globalization and technological change very well over a 30- and 40-year period," Mr. Hubbard explained. "We're probably not going to do it again."

That has helped spark an investment boom in computing, and a burst of new growth for the broader economy, which Mr. Trump has tried to maximize. Through a series of executive orders, signed over the last 11 months, Mr. Trump has moved to eliminate regulatory guardrails and make it easier for tech companies to build data centers, power their operations, sell computer chips and source critical materials.
