I work in healthcare IT, we develop medical systems which help physicians to help people. It sounds like a good field to work in, but it's still about money in the end, looking for ways to maximise profits, because we live in a capitalist system. As long as profits play the main role, there always is a dark side.
I agree, there are no good billionaires. The moment they donate all their billions they are good but they are no billionaires anymore. "good" and "billionaire" are mutually exclusive.
You've forgot the actual "engineering" parts which distinguish programmers from engineers: requirements engineering, software architecture and complex problem solving
There is a huge difference between a "programmer" who just codes, and a software engineer, who studied computer science and learned the skills for problem solving as an engineer. The latter is protected in many countries.
Crazy to think that there are people who need to go on such walks, because they do not already walk enough in their day to day lives. Do they never leave their homes? Or do they use their cars for everything?
Our culture sucks, their ignorance is a blessing in this case.
