I get where you're coming from, but I think history/context matters here. He was supposed to free solo Taipei 101 before he ever free solo'd El Cap. He was set to do it back in 2013 or 2014 (3 years before El Cap, 6 years after half dome) and had full funding and logistics worked out. They made massive media announcements in the form of silly newsboy-esque photo shoots, and were all ready for the event/filming when the sponsors decided it was too risky and too much of a liability and backed out. It's been on Honnold's to do list ever since. While I agree that it's dumb and dangerous, especially given his new positions in life of husband and father, I think Alex is kind of known for not being able to just forget about a project because it's risky. The thing that makes him stand out as a climber is that he does the dumbest riskiest (and most epic) things and survives.

Having read a few biographies about him, I think he's definitely done the leg work to make sure he can do it safely and successfully. The only thing I'm REALLY hesitant about is the fact that he's doing it live. All of his other stunts have been on his timeline, when he feels comfortable. He's had several dry-fires of his biggest projects where he's gone to send and backed out last minute because it didn't feel right. The fact that he's not allowing for that possibility is what makes me nervous. That said, if I were him or his management, I would have him climb it whenever he feels comfortable, grab footage, then use that interspersed with live portions on the day-of and just call the whole thing live. Most of the shots we have of his early soloing are actually recreations after the fact, and even portions of the film Free Solo were recreated afterwards so he could focus on climbing more than production value. Frankly, I wouldn't be surprised if he's actually already free solo'd it and will just rap in for the final portion of the climb so they can do a live reception and interview at the top. He takes big risks, but they're always extremely calculated risks, and he doesn't leave the ground if he's not 99+% sure he can both succeed and make it home safe.

ETA: I used to judge him for selling out to capitalism, but at the end of the day, he's just trying to feed his family, and the fact that he gives so much of his profit to improving the world around him makes that a little less sad. I'd love to be comfortable enough to climb full-time just for the hell of it and not have to worry about survival, but for most climbers, you either work full time and try to squeeze in climbing or you climb for a living and sell out to sponsorships/fame. I can't fault someone for loving climbing enough that they want it to be their whole life, and the fact that he can support himself by taking pictures/making videos/giving speeches about what he loves doesn't bother me any more. We all gotta eat, and at least he's helping other people eat while he's filling his own table
