I'm not someone who downvoted you, but you can't just assume everyone else sees value in the same things as you. Perhaps those votes are from people who find the whole digression about cryonics off-topic and boring?

So any topic that I don't like I downvote even if other people like to discuss about it and it's about science. Cool I guess HN is not fairing better than reddit here.

People fear what they do not understand. This has been happening to me for the 25 years I have been on the internet. It does not happen when people talk to me in person.

Most people come to the internet to validate their existence. I come to dismantle it.
