Interesting you prefer hydraulic specifically, even the disc brake zealots mostly agree mechanical is more reliable and easier to maintain.
This is absolutely the opposite of my experience and the experience of anybody I've ever met who has actually ridden a bicycle before.

I can stop faster with less effort. > Rim Brakes Are Better For Most Riders Most Of The Time I don't need any brakes at all most of the time either, but when I need them I really need them.
And not to mention how much effortless it is to apply the brakes compared to cable brakes where there's friction within the cable hose.
I can't go back to cable brakes after using disc brakes. Even for normal grocery trips. Nothing recreational.

> But 700x28 is really the maximum tire size you can possibly fit with rim brakes This is patently false. Mountain bikes have been running tires over twice as wide on rim brakes for decades. I had one growing up in the 90s. Perhaps you mean caliper brakes? Even if so, I currently run 700x28c on my 10yo racing bike, I don't think I'd have any trouble going up a size or two.
700x28 is the maximum my rim brake bike can fit. I wasn't as clear as I could have been. Other rim brake assembly types can fit more, but those are even less common on modern road groupsets.
Between 2015 and 2020 we came back on skinny tires and wanted more than 28mm. This was the same time road cycling moved to disc brakes. Most bikes with rim brakes are still using calipers, cantilevers are not coming back. If you want more than 28mm, you will want disc brakes.

On a disc brake bike, calipers are ~100g, rotors ~120g, and then you’ve got ~150g of tubing/fluid. They’re certainly heavier, but the components don’t even add up to 1000g, nevermind when you offset the rim brake component weights.
And the frame reinforcements for caliper mounts, the extra spokes, the disc compatible hubs, the thru axles, the heavier brake levers, and probably some stuff I'm missing. No need to get emotional over this stuff, I love my hydraulic discs but they are heavier at comparable price points. It's also not particularly important to have a bike weigh a bit more, I was just letting the OC know that he was wrong on that aspe…
So to add it all up you’re looking at 770g in components/additions, offset by 75g skewers, 310g calipers, and an added 25g or so per rim for the brake track. So discs are naively something like +335g. I obviously agree it’s a heavier system, but I don’t think ballparking the penalty as triple what it actually is is reasonable.
I switched to tubeless on rim brakes and had a downhill blowout from pressure cooking the sealant. I also tend to abuse my rims and rarely true them, so my brakes are always loose or rubbing. Both these problems may go away with carbon rims, but pincher brakes with carbon pads don’t have much stopping power. Discs do, but they are heavy and put extra torque and heat stresses on the frame, as well as a twisting moment…

Biking for 40+ years from around the neighborhood to centuries, and do maintenance except cost-prohibitive procedures. I have road and mountain bikes with rim brakes (grew up with them), disc brakes, and a 4kW scooter with disc brakes and regenerative braking. Disc brakes are high maintenance: oil (leaks and water content), pads, and springs. Rim brakes are more-or-less maintenance-free except cleaning the rims maybe…

If you have the money to pay someone else to deal with the maintenance, then sure I guess. I do my own work and don't want to deal with bleeding brakes and all the extra tools that are required for that.

If you're not an avid cyclist please take this article with a grain of salt. It's largely understood that disc brakes are better, full stop. A few guys in my cycling group who are still on rim brakes will not take the really fun descents, even when it's completely dry. They don't trust them. Pad fade, overheating brake surfaces causing de-lamination and popping inner tubes. So, sure, if all you're ever going to do is…
That's a silly argument. The people crushing it on a downhill aren't using their brakes. I road/raced on rim brakes for decades and brakes were my least concern.
