If you were on your death bed it'd be a pretty attractive prospect, but in the end it'd be unfulfilling. All of your experiences would occur in set parameters, you couldn't really accomplish anything or leave any lasting impact on anything.
My feeling about Inner Light is that through the experience, his neural activity didn't really change, and his experience was compartmentalized. So when he came to, even though he felt like he'd gone through a lifetime, the same thoughts were fresh in his head.
When I go on vacation to a place I haven't been in years, I remember things I did last time I was there like it just happened. Memory responds to cues very well.
When O'brien experienced similar tech (although Argrathi vs Kataan), he clearly reacted as if he really had just experienced a real-life 20 year sentence and was just released. Are you saying the Kataan tech is really different? Somehow I think that if the Kataan probe were used instead on O'brien (but with the same "prison program"), I would be surprised if it would make any difference.
You seem to think the Argrathi vs Kataan techs are "different" but I'm not sure why that would be.
