If you had a choice would you become immortal or die naturally?

Haha, perhaps, assuming that you wouldn't have to wait for technological advancement to obtain the necessary tools for carrying out experiments. Otherwise, being immortal has no benefit as you are subject to time itself.

When the sun eventually explodes I'll be like what now.

I did think of that. The Earth falls into the sun before the sun explodes. You'd have to move star system(wouldn't be much fun floating around in vacuum for eternity).

Yes I might have to wait for the necessary technologies to perform some experiments, but I could find stuff to do in the meantime and in my opinion it would be better than never even seeing the advancements. To an immortal being any finite time delay is negligible.

Immortal, but only if it meant I was immune to things that come with death like illness and disease.

The delay would be infinite..

I mean the delay before obtaining any particular technology.

Yes, but because there is always a delay in time, you will never be able to attain your goal. You will remain incomplete in knowledge

If it were possible to get cancer or illness then wouldn't that be more reason to want to be immortal? You could live normally for as long as would be possible (even outlive the age expectancy as long as you don't get a disease), then when you seek death or get bored of life and find it tormenting, you'd have the option of death.

Although imo that wouldn't be true immortality. If immortality meant that you just had the potential to live forever but could still be killed then that wouldnt be immortality.

Forget the people you know and love passing away. What happens when your disembodied consciousness is floating improbably in the void and you haven't seen so much as a gamma wave come past in the last 900 quadrillion years?
