You've probably seen the promos on Netflix:  superstar climber Alex Honnold will attempt to climb one of the tallest buildings in the world TONIGHT.  Live.  No ropes.  Netflix will air it on a 10-second delay, but that doesn't fully cover all of safety and ethical concerns for what Honnold is doing.  Honnold -- considered one of the best climbers in the world -- shot to fame with the Oscar-winning documentary "Free Solo," which documented his no-ropes climb up Yosemite's Dawn Wall.  He's the only person to ever free solo the Dawn Wall, considered the holy grail of climbing. Tonight's broadcast comes with controversy and criticism, especially now that Honnold is a husband and father of two young girls.
