You didn't watch the video... clearly. He refutes all of your rather mundane arguments with ease. Everything you said, without a doubt is fatalism. You say you're accepting reality. You're not. You're accepting things as they are now, and refusing to believe things could change.
Death is not inevitable. It's just an, as of yet, unsolved problem. If I were to tell you a meteor was heading towards earth, and was scheduled to hit us, killing everyone alive in 100yrs, would you say "Well, we've never stopped a meteor before, we'd better just accept it!"?? Of course not... but that's what we're saying. In 100yrs everyone alive today WILL be killed... not by a meteor, but by aging. For a hell of a lot less money than it would take to stop a celestial object, we could stop aging. So lets stop burring our heads in the sand and take care o fit. The problem of aging will be solved, and not too far off in the future. Likely it will be too late for us, but not for our children or our grandchildren. So lets do it.
