> choosing to pick the negatives

Yes of course there are positives. Don't worry, we have never let negative consequences hold back progress before.

But the blind optimism is staggering, and let's get philosophical: what's the ultimate good, objectively? (Subjectively obviously _I_ and _you_ think it's that we get to be around for longer.) But objectively, from a humanity standpoint, is it (1) the most people in existence, (2) the most people to ever have existed, (3) the most consciousness, (4) the most happiness? Etc.

If we start letting people live forever, over a long time, because of resources, fewer people will ultimately exist. We'll also have slower progress because old ideas will live longer. It's very hubristic to think we've peaked, and it's inevitable that the first live-forever generation will put the brakes on progress/change.

I'd say those downsides far outweigh the upsides you've proposed.
