In the middle 3rd millennium, aging will be gone and death will be rare

In several comments here, you use the word "will" a lot. It's possible, but it makes you sound like a crazy prophet. No-one knows for sure how the future will play out.

Replace "will" with "will probably, based on a variety of assumptions, most notably continued technical progress in the long term". Economy of words.
