Belaying a lead climber is much less straightforward than belaying a top roper, so that's all true assuming he has an excellent belayer, which I'm sure Adam does. That being said mistakes still happen; just look at Sara Al Qunaibet's recentish fall. Alex Honnold was also dropped by his (at the time) girlfriend and suffered injury. He was lucky to be on the first pitch of a multi pitch climb at the time.

It's absolutely true that human error can occur, and it does happen sometimes. Of course, nobody is doing big-wall climbing with a grigri (although in Sara Al Qunaibets case there was even a grigri that the coach was able to misuse...). I still feel safer taking a fall with a belayer I trust than I do driving behind some stranger that's driving erratically. The most dangerous part of any climb on pre-bolted route is likely the drive to the crag.

Totally agree. Feeding through a Grigri in order to lead belay necessitates disabling the autolockimg behavior of the device and creates an opportunity for a fall to the ground if the climber loses it unexpectedly. Belaying with an ATC still isn't a replacement for vigilance, though. Catching a lead fall with minimal fall distance requires a combination of constant attention, deep understanding of the route, its cruxes, and your climber, anticipation of the fall based on your observation of the climber, and bulletproof mechanical memory of the process. Even still, runout is a thing on many routes. I would add on to your statement; the most dangerous part may be the drive to the crag (or perhaps, a scramble approach) but the second most dangerous part may well be the climb to the first draw.

I agree with you on the by and large, but wouldn't describe belaying a lead climber as quite as demanding as you do (by all means, be vigilant at all times, someone's life is in your hands!). You can feed out rope from a grigri without putting a thumb in the mechanism, but it's a bit more of a hassle, and requires a bit more getting used to. I'm pretty much always belayed by my SO (who's a much better belayer than me, and doesn't disable the grigri when feeding) and get stressed out if someone else is belaying me and I notice that they're disabling the grigri while feeding rope.

It's definitely true that by far most injuries in climbing occur on the first 1-3 bolts, when it's still possible to hit the ground if you have too much slack or a bit run out bolts. Long run outs higher up can feel sketchy, but even a >5m fall high in the wall isn't really dangerous unless there are outcroppings or other stuff you can hit. Ankles might still take a beating though...
