1. I believe that if it is possible, we'll do it. Humanity is like that. Even if you ban it in one country, it'll be done in another. If it offers an advantage, it will be done by someone looking to have that advantage.
2. I don't believe it will ever give us "Immortality". At best, it will extend our lifespan by quite a bit.
3. 2040's a bit optimistic. I fully expect that by 2040 we'll have good artificial limbs, but immortality and super-powers? I doubt it. That seems more likely in 2080 or 2100. Assuming, of course, we haven't destroyed ourselves as a species by that point.
