Other than paying much smarter, more skilled, and generally better people to do stuff and take credit for their work, throwing out random shit and demanding that others make it happen is literally ALL he's done professionally since he made a Space Invaders clone as a kid. That and self-promoting.

Being rich already; ruthless opportunism at the cost of the health, happiness, and often lives of others; and shamelessly relentless propaganda is how billionaires are made.

Always has been.
