I see two issues here,
1 - Another incident where the pilot simply passes out. Too many accidents looking back the last year with no real explanation why they got incapacitated. The Vaccination with Thrombosis as one of the most common “side affects” may to be blamed here. I know more people suffering from side affects than of people who suffered from the actual C.
2 - Without having the full conversation to follow, it is impossible to tell what really went on. Most likely the Caravan was on autopilot. With a good instructor / controller, using the heading bug, the altitude hold diengaged and carefully managing the power, I could see how to get a caravan down on a big airport.
Autolanding with autopilot and Garmin equipment is already a reality with more complex aircraft. The 208 more or less slammed on the runway and it will need a nose gear inspection after this high speed touch down with no flaps. Future will show if this was just another stunt or a real emergency. Hope to hear about how the pilot is doing and what the cause of his “passing out” was.
