I don't know. I can't even watch most vloggers to begin with.
One third of the video is introduction - who I am, how I became aware of this issue, why it is important to me and why it should be important to you and how they came up with the title of the video on and on and on.
Some can't seem to speak without using sentence enhancers such as yeah, um, like, sorta, ya know, oh or some combination thereof. There was a time when no self respecting public speaker would ever use such words but now we hear them during presidential debates.
There are a few very credible vloggers such as Raoul Luescher who talks about carbon fiber and is actually a materials engineer with experience in aircraft composite fabrication. Most vloggers are just some guy nobody ever heard of trying to monetize a bunch of long winded opinions.

Yeah? Dragging your feet will stop your car? Good luck with that.
The argument that rim brakes are an antiquated tech is fine. Guess what else is antiquated tech? The gas engine. Why do most people still drive them? Either their driving conditions require it or they'd rather not pay a premium for an electric car.
The same is relevant to discs. Why would you pay a premium (in most cases) for something that isn't going to benefit you aside from in very specific use cases?

Another thing........ Are those cycling shades or swim goggles? He needs a snorkel to complete the look. Maybe he is a triathlete. He could wear those in both the water and on the bike. Save some time in transition. In all honesty, this is about all I see when I watch that video.

- My first bike had a backpedal actuated coaster brake and I thought no need for more as I could skid whenever I wanted
- Then I got a Raleigh 3 speed chopper with steel side pull brakes and thought now brakes on both front and back and levers just like a motorcycle and how could you want more
- Followed by a Peugeot with Mafac Racer center pulls on serrated steel rims amazing.
- Another Raleigh this time with Universal alloy sidepulls on alloy rims what a step up.
- A Marinoni with Campagnolo Nuevo Record Brakes another improvement.
- Roberts with Dura Ace dual pivot Brakes made The previous feel like you were dragging your shoes.
- Colnago C60 with Super Record on Mavic Exalith rims wow what a noticeable improvement.
- Now on Dura Ace Disc and I love them and what a improvement from previous.
I cant wait to what the future will bring!

Bingo!
My 1970 Olds Cutlass had 4 wheel drum brakes, Never had a problem stopping except once while racing another car and trying to stop on the other side of a hill at 90 mph. Good thing I had room. I finally figured out what brake fade was.
I think of bike disc brakes like drums on those old cars. Under extreme conditions, Disc brakes are may have a distinct advantage to commuters and recreational cyclist's descending moderately steep hills in the rain. The rim brakes on my 2018 Giant Sedona have plenty of stopping power and very good modulation dry, are fine in rain too on flat roads, Just take a little more pressure on the brake levers. I haven't tried them descending moderately steep hills in the rain though.

Just go with whatever you like most... I don't see why people would need to argue on that. The fact is that, rim brakes lovers will not change their mind and neither will disc brake lovers. I do not believe that performance is why people are going for disc brakes. This is BS.
Personally, I like disc brakes for the look. I don't use them often, but they're there when I need them. I wouldn't probably notice a difference using rim brakes.

Since I live in South Florida, where there are no hills, except for bridge approaches/descents, looks like rim brakes are just fine.
Also, there are many nice parks with paved bike paths, so there is no need to ride on our s****y roads.

I've never had a problem on this ride with rim brakes even in the rain/fog. Went down it one year on Mafac Racers in heavy rain. It was a little hairy that time. Of course, I don't use carbon rims either. I'm about 230lbs with rider/bike/gear.

- Disc brakes aren't hard to maintain. In fact, if you keep your bike long enough, cable-actuated brakes require more maintenance. Hydraulic road discs, in my experience over the last five years, require zero maintenance if set up properly. Cables eventually fray, stretch, and break. I've never had to maintain a road disc except to replace pads (the same as I would a rim brake).
I'm skeptical of the 30g claim. Apples to apples comparisons I've seen are closer to 400g. Not that either number is significant to the average recreational rider.

So are you saying mechanical disks are more maintenance than rim brakes and hydraulics are the same? My experience is that BB7's are many multiples more maintenance than rim brakes. Agree that bleeding hoses and replacing cables is probably a wash.

I've been enjoying watching YouTube videos of people building "dream bikes" from frame up. The routing, cutting, and fitting hydraulic systems looks like a pain in the ass, but the bleeding, with the right tools, looks WAY simpler and much faster than replacing cables.

Nope, it was dry, but I still prefer the discs when it's dry, but my rim brake road bike has carbon wheels. Granted, braking performance on the road bike with alloys and koolstop pads is really good, but it's easier to swap the road wheels on the gravel bike than it is to swap wheels and brake pads on the road bike. Sheer braking force may be the same, or similar, but the modulation and ease of braking can't be discounted either. I'm not rushing out to buy a new road bike just so I can have disc brakes, but when the time does come for a replacement/upgrade, it'll have discs.

What are you doing that is taking so much time to maintain BB7's? If its dry every couple hundred miles you have to turn 2 knobs 1 click. About the same frequency as you have to turn the tension knob on a caliper brake. If its wet a bit more often on the BB7s but for rim brakes you have to constantly wipe down the rims and pads and pick out metal shards if you want the rim to last a long time.
