Frederick, I found Kardeshev Technologies. I found the written content almost impossible to read because of the lack of contrast between the text and the background. Maybe you are able to influence the web designer to correct that? As for what they do, I am wholly supportive. I don't think that alters my reaction to your claim. Nothing can be made useful to humanity - to sustain life - without the input of human labour. That is an inescapable fact.
