It's not stupid. Though I'm sure you see why digital VU like the one in the video fail - the displays used are simply inadequate. You need something with far higher refresh rates, and motion blur/ghosting mitigated.
EDIT: Btw any electrical people in the house want to explain to me, why the hell is it so hard to get VU meteres on products that don't cost an arm and a leg? Is it really that hard to do this?
I hate when I look back in the past, when manufacturing, and just life in general was far more laborious per ounce of energy expended, we were able to do all those things. But now in the present/future when the costs of things have fallen, and we can do more with less resources.. NOW for some DAMN reason no one can do anything that should be easy to do because it's relatively old and simple after all these advancements.
What is up with that?
