Truth is not a popularity vote.
It does not matter how many people are for it or against it.
Hey we agree on something for once. I am with you on this one something is true or false moral or immoral inherently and objectivity and it really does not matter if it is a majority or a minority that is able see to understand that truth.
However, I am surprised to see this line argument from you. It was not that long ago when you said this.
morality is relative and is not absolute.
So are you a believer now in objective truth and objective morality? The scientific method is objective. This is the best epistemic tool we have to discover what is true and what is false.
Subjective opinions of minority or majority are just that, subjective, and can be dismissed if they cannot be validated objectively.
Morality is temporal and is cultural. We have plenty of evidence to support this fact.
We strive to improve our morality to cause the least harm.
Morality aside, I am not sure we'll ever move up on the Kardashev scale. Unless we drop the ancient myths and embrace science and technology. You are an MD and you are against stem cell research, a case in point. Imagine what all other less educated simpletons think
of science. The majority of people do not even understand basic concepts (BADecker etc.). Look at the Flat Earth 'syndrome'. The Internet is a two-edge sword I guess.
Another problem I see is rampant nationalism, political tribalism, and remnants of ancient myths that will slow us down in the best case, or completely wipe out human species in the worst case.
The biggest issue is our exponential human population growth, but nobody wants to talk about that.
We may just outbreed ourselves into another population bottleneck.
