I dunno about this. It's a 50-50 belief. 50% thinks immortality is great. The other 50% believes the other way. http://www.debate.org/opinions/should-scientists-pursue-immortalityAnyway, I'm a bit off topic.
I think it's gonna come down to Gosho's belief about this. If he thinks immortality is great, then it's pretty debunked but otherwise, it's plausible. We have no way of knowing it, though.
