If you base it on scientific facts, yes. But actually science is not about facts but about a method of understanding that produces "factual knowledge". Yeah, as you say, even the understanding of understanding evolves, but we just need to learn to "design things that evolve"... and I think it's orders of magnitudes easier to do this "in the world of pure memes" with something like a philosophy, than in the physical world with something like a self-replicating mutating robot. Yeah, just as with such a robot you'd have to give up things like "control over it", with such a philosophy-religion you may have to give up things like "moral values", but that's ok imho, since you can have those separately... The only thing that makes a "cult" "bad" is lack of freedom and flexibility, and this is "by design" for most cults.
