I apologize for breaking your comment down into quotes.

So, empathy like I said.

Incorrect, it can be entirely selfish and rational, because helping others also helps you.

Why do you value the technological advancement of the human race? How do you determine what is advancement, and what is regression?

I thought I explained that pretty well. Life has the meaning we choose, technology gives more choices.

Why place emphasis on satisfaction and aversion to harm? How do you determine the relative levels of satisfaction and harm except through empathy?

I also explained that. It’s the most efficient method. It is the time-proven way to accomplish the goal of furtherment of technology, and satisfaction is also our primary motive as animals. All methods which fail this simple test, whether or not they avert harm for others, inevitably fail on a societal level. How we measure it, satisfaction and harm, is by actually measuring it via communication. Humanity has developed means of quantifying happiness and wellbeing, of assessing the wants and needs of individuals and society as a whole.

I feel like I’m just repeating myself.
