Because it's a colloquialism, and because despite that "No is a complete sentence" post from earlier this week (last week?), it often comes across across as rude, unnecessarily harsh, and over time will make people think of you as an asshole.
Yes, LN is different. The Lightning Network consists of channels with funds held in a 2-of-2 multisig, so the only way one participant can have a quorum of signatures is if they already own both ends of the channel. There are Bitcoin sidechains that have a similar federation of validators, such as Liquid.
How are we not a cancer on the planet, though?
We are literally responsible for the 6th largest mass extinction in history, based on greed for fossil fuels, animal products & rearing unnecessary children who serve the Need Machine (life/DNA) needlessly, and this is with all the knowledge and technology we have, in fact the more we had and the more we destroyed to get here.
We are like addicts to the drug of life, too scared of admiting we have to stop spawning other addicts as a mean to an unreachable end.
We do not accomplish anything by "creating a need and satisfying it". We do not accomplish anything by creating every problem and solving some of them (or even all of them).
Life is a cancer on this planet. Life is extractive of the natural resources. Name a single life form that leaves the planet “better” than if it had not been there?
Is your preference that Earth be devoid of life? Looks like Mars or Venus? And nothing of consequence exists there?
That’s obviously not what you meant, but it’s the natural extension of your argument.
If you think about it, the planet doesn’t give a shit if we live or die. It is not sentient. Neither does the Sun, nor the Milky Way, or the other galaxies. Whether we live or die, blow the planet up or not, is irrelevant to it all.
Somehow, humanity was given a gift. By God or the universe, but you have to admit that it’s pretty miraculous. And the fact that you and I are debating each other about the merits of humanity’s continued existence over the Internet is pretty wild too. But again, it is insignificant to the overall timeline of the universe.
Given that it’s all meaningless, why not spend your time here giving it meaning? If you believe we are a cancer, why not spend your time ensuring that you are not that cancer?
Furthermore, children are a fantastic way to continue contributing to society’s search for meaning. If you don’t want to have children, to me that indicates that you don’t feel you provide value.
I’m here to tell you that you do. And that you’d probably be a good parent, that would produce a child that also provides value.
