Not sure why you've been downvoted, because you bring up valid points.

I have one to add, let's imagine that we science our way into living much longer - our bodies may continue to live, but what state will our minds maintain? Keeping a body alive by no means guarantees a healthy mind.

We might discover that despite the healthy condition of the human body, no sense of self is able to survive over a few hundreds years before losing coherency. Perhaps the human brain just wasn't designed to contain more than one lifetime. In such a scenario we would be sitting on a whole lot of perfectly healthy vegetables who will continue to live very long lives thereafter. I for one never want to live as a vegetable. My dad told me the same thing, if ever he's a vegetable then pull the plug. I would do that for him, and I hope someone would do it for me if the day came.

People don't like facing up to the negative consequences of new technologies. It forces them to consider the wild concept of "other people"
