You sound surprised. Death and aging are engineering problems. This is a site filled with people who believe engineering problems can be solved. What Aubrey brings to the table is reminding us of this and daring to attempt it. Fixes are possible.
The tendency to see solvable technical problems where there aren't necessarily any. Exemplified by those financially successful technical people who purchase sports franchises and then always manage them into the ground, having approached the enterprise as an engineering problem. Also evidenced by the horrendous record of technocratic governments and affiliated political philosophies formed by technical people.
Simple, no, but I'll bite on the second half of your statement "that there's even a chance of it happening this century" because the chance is there. Curing aging is incremental. Life expectancy at birth in the United States in 1900 was 47 years, today it's 76.
It's fascinating--you're so confident in your negativity that you'll predict 100 years out! I couldn't have imagined 30 years ago I'd be wasting time on something called the internet responding to a troll calling people "suckers" in a hacker forum, but here I am. Shame on me for responding, really. Good night...
Death sucks, let's get rid of it.
