Semi trucks with EV can outperform a comparable ICE

The thing is as new successful technology was developed, it was typically better than what it was replacing.
If the Lightning is truly a fail it will not last long.

Remember there were not many paved roads or even construction equipment to build them.
Somehow we managed to build roads, gas stations, and an auto industry.
We even took it a step further and built the airplane
It won't be next week but I think we'll find a way to develop a battery and charging solutions over the next 20 years or so.
Color TV,cell phones,computers and the internet have all been introduced since I was born and have dramatically changed the way we live and think.
To think we cannot develop battery technology is silly.

Do you believe EV is not a step forward?

Finally, a point on batteries - soon batteries will be Sodium Ion - salt, not Lithium - better for the environment and more plentiful.
