I did my first dives in Dahab, Egypt including at the Blue Hole. This location was my first experience with narcosis; but, it was planned. Myself, my father, and our instructor dove down to 45m and he handed me a whiteboard to write on. He asked me very basic questions like how to spell your name and I remember really having to think hard to answer.
In general, if you are diving to see fish, it's rare to go past 20-30m (the minimum depth to exp. narcosis). The visibility is worse the deeper you go and typically if there is a reef at 30m there is also one at 15m where your oxygen will last longer, less cold, etc...
I don't think diving needs to be dangerous to be enjoyed. It's about seeing an entirely new world and the moving in the medium of water. The people who've perished at the Blue Hole are taking an extraordinary amount of risk - diving solo, descending to 150m - for 'achievement' purposes and I understand Omar's frustration.
