There will be fallout.
The commitments being made by the tech billionaires to the Trump Regime are, in toto, unattainable. Between the AI 3 card monte game, Larry (et fils), Zilcherberg, there have been about $2.2T US committed to various bullshit enterprises. Furthermore, in the various Celebrity Presidential Parades about the planet, there are bout $4.4T to $6.8T US commitments to purchase *energy* (variously, crude, refined petroleum, LNG etc) over the next 5 years.
Taken individually any of these commitments is possible, but collectively they result in the US having 0 barrels of oil, 0 CM of natural gas and almost 0 electrical capacity for the people living, working and quite likely dying in the US.
The US economy is in free fall, and is likely already in a recession, to wit, the Fed actually DID lower the prime (admittedly only a quarter point) while there is very clearly more being spent (several TIMES more) by the entirety of the US than is coming in from the collective incomes of business, government, individuals and the financial groups.
Thus this "We will build it and they will come" bullshit is precisely bullshit.
