These improvements will not require something to be changed fundamentally or drastically, just improvements that are already working in lab and controlled settings.
Companies are pouring billions of dollars into battery technology, electric motors are very efficient now, so I just am surprised about the resistance to EVs in this forum.

Don't count me as part of the resistance; I'm among the biggest fans of all things electric. Because I love electric stuff so much, I'm among the biggest critics of the things that suck about them.
Batteries contain 1% of the energy as gasoline by weight. That's not a trivial fact. Then a battery is essentially a fuel tank; an enormously expensive fuel tank. It's also bulky and heavy. It's a fuel tank that shouldn't be filled completely or drained all the way, because it accelerates capacity loss. Finally, it's a fuel tank that requires thermal management. It can't get too hot or too cold.
There was a guy on another forum saying he wanted a EV truck that goes 500 miles. As I explained, a 500 mile range pickup would have a 250 kWh battery. This battery alone would cost $32,000 to manufacture (who knows the retail cost). It would weigh 4,000 lbs, or more than a typical sedan. The whole rig would be somewhere around 10,000 lbs.
The bigger the battery, the more capacity that is lost over time (degradation is roughly in proportion to battery size).
Tell me which chemical equations tell you that replacing ICE with battery technology is within the realm of physics and science. Stating it doesn't make it so.
