I'm 27 for the record.
Just feeling increasingly hopeless and that shit sucked when I was born and it'll still suck, possibly even more, by the time I die. Even if I live to be 100.
That humanity will reach a Star Trek-esque utopia eventually, but I was unlucky and born too early when everything's still terrible.
73 years is a long fucking time.
If you asked a young Russian peasant in 1847 if they thought the Russian Empire would fall in their life time what do you think they'd say? What about a plantation slave in the same era? How much hope do you think they'd have they or their chldren would ever see abolition? Or if you asked an Indian farmer if they'd live to see the fall of the British Empire?
New advances in communications and manufacturing technologies have almost without exception led to massive social change. The advent of the internet, the unceasing advance of automation and the impending climate apocalypse have all but ensured the next half century will be one of greater social change than humanity has ever before witnessed. It's our responsibilty to steer that change in the right direction. Things are almost certainly going to get ugly but we have in front of us the opportunity to effect greater change and do more good for humanity than anyone before us has ever had.
Keep fighting the good fight, keep hope alive and with any luck what we achieve in this century will make Gene Roddenberry seem like an unimaginative pessimist.
