(Ad)President Donald Trump made headlines last month with a staggering claim. He stated that since taking office, more than $12 trillion in private investments into America have been “practically committed” on his watch. "Nobody's ever seen numbers like we have," he said, crediting his agenda of tariffs, tax cuts, and deregulation with making the difference. If true, the figure would indeed be astonishing – potentially tripling the roughly $4 trillion in gross private investment the US reported all of last year.That means that you could still get in early on the biggest technological shift in history.
