bc2025 Why not post a link to the video, instead of being vague like "one of my favorite reviewers"? ;-)
Then, referring vaguely to "another product at half the cost"
We can only vaguely reply then. Yes, you will have certain people that will rip apart anything they don't consider to be the best, but at least the rest of us know what you're looking at.
My experience in auto-shifting is only in the muggle bike world so far. Road bikes with the shifting motor built into the derailleur and a little cable going into the bike to tap into a remote battery. The problem is that when those batteries die, you're done; you've got a single speed. They're refining them so that they give noticeable warnings as the battery discharges. These things should not be an issue on eBikes though, as they have a robust power system. Even when the bike's battery is dead enough to not power the motor, there's plenty left for small electronics like the display and electronic shifting.
This is what Aventon was getting at in the ad copy for the Aventure M:

They also have automatic assistance setting, which I'm not sure how that is different than torque sensing. My Yamaha Wabash RT has it and reviewers seem to love it, but I don't. I like to manually be able to control how much more torque it gives. When I want a little more, I either pedal harder or tap the button to go up an assist level.
On the other hand, I've been riding bikes for 40 years and shifting them for 30. I'm technically-minded and have an intuitive understanding of how bike gearing works. A lot of people don't. Maybe this is a good thing for them.
You have to remember that a lot of these reviewers are compensated by the manufacturers. Usually the ones with really polished videos.
