"Dan Ives told CNN that it would take about $30 billion and three years for Apple to move its global supply chain back to American soil."

You have misquoted Ives. He said it would take $30billion and three years for Apple to move 10% of iPhone production to the US.

“Apple has already announced a $500 billion investment in the U.S. along with Trump in February,” Ives noted. “The reality is it would take 3 years and $30 billion dollars in our estimation to move even 10% of its supply chain from Asia to the U.S. with major disruption in the process."

With both less revenue due to demand destruction and less earnings due to higher taxes, Apple will have less money to invest in American manufacturing. I'd be surprised if Apple actually spends the $500 billion it committed to US expansion under the Biden administration. Would any of you invest in a future being whipsawed about by the mercurial Trump?

If I understand correctly (and there's little reason to believe I do, this is complex), iPhones will have significantly higher tariffs (54%) than Samsung phones (25%). Throwing the bus keys to Samsung, so they can drive over Apple, doesn't seem very MAGA to me. I expect an adjustment here, either in the tariffs or at the mid-term polls.

I'm afraid the AI explanation for why MagSafe magnets don't affect RF propagation is... wrong. Static magnetic fields don't affect electromagnetic waves. If they did, you'd see them affecting visible light, which is also EM radiation. Both RF and visible light are created by photons, which have no charge and are therefore unaffected by static magnetic fields.

No inverse-square explanation is needed for an effect that does not exist.

To the extent that a MagSafe magnet ring might be conductive (perhaps via a mounting materials or protective coatings), it could affect iPhone RF propagation, but there's already a charging coil on the phone's back that's certainly a far bigger influence.

ETA: The iPhone's charging coil operates at between 80 and 360KHz. The resulting dynamic magnetic field will interact with the iPhone's RF system, but the frequencies (GHz vs KHz) are so far apart that it's not an issue.
