Ima just going to add this: in the first couple days of having my brand spanking new disc-equipped Domane, I had a near miss that would have instead been a bad, bad accident had I been running rim brakes. The disc brakes allowed me to modulate the braking so finely, smoothly, and intuitively, that my tires squalled but never fully locked up; and that combined with the fraction of a second it takes rim brakes to fully bite, would have ended up with me over the hood of a car that decided to U-turn in front of me without warning.
Sure, I know, this was only one dramatic incident in thousands of miles of riding, but the disc brakes literally literally saved me from grievous injury or worse: destroying my brand new bike.
Me? I'll never go back to rim brakes.

If you're riding for fitness, and you're riding as fast as you can all the time...
You're doing it wrong... says just about every single fitness expert out there.
Ever heard of a rest day? Besides... riding DOWNHILL doesn't help with your fitness... You may want to try riding up the hill instead. (And in that case, brakes don't matter...)
Most people are smart enough to realize that going as fast as you can means you'll wreck more often. Wrecking more often means more time off of the bike and lower fitness overall.
And I'll say this for the millionth time.
I highly doubt anybody riding for fitness is using their brakes/tires/grip to their full potential.
In order to be the fastest through the corners, you need to do 3 things.
Choose the right line.
Brake as late and as hard as possible.
Carry as much speed through the turn as possible.
When you're cruising down the hill, are you braking as late as physically possible, lifting your back wheel slightly off the ground before every turn? Are you carrying as much speed through each turn so much so that if you were 1 kph faster your front wheel would wash out?
If the answer to either of those questions was "No" then you will actually be slower with disc brakes. Hell, you'd be slower anyway in the dry (according to the video.)
Although the macho attitude of "I ride as fast as I possibly can all the time" is quite hilarious.

People say they want choices, but when you give them choices, they freak out and demand everyone support Their choices ....

And if you had ever actually ridden down a steep mountain road in the rain, going fast without even pedaling, you wouldn't have made that statement.

By the logic of the anti-disc contingent, Bettiol would have won instead of finishing 64th in the TT, had those evil disc brakes not been slowing him down with their anchor-like weight and egregious lack of aero. Surely no remarks about the 132 riders that finished behind him, though.

Touched on slightly is the deal of rotational enertia. A rim designed for a bike with disc brakes can be more aero, lighter, and stronger if a brake surface is not needed. Therefore a bike with discs, and a proper disc brake rim will accelerate faster, because of less rotational enertia. If you are racing a bike that will accelerate faster in the ending sprint, you will be the winner. Think about that.
