I went from being a largely self taught software dev with a small 1-man software business to working as a nurse in the US, and a lot of the motivation to make that change was that I wanted to spend my time doing work that I felt genuinely made the world better. Tech has incredible potential for good but the actual industry itself in my eyes has extremely perverse incentives and no strong moral foundation like that which exists in nursing/healthcare. Nurses broadly consider themselves to be patient advocates and the voice for people who often can't have their own voice. As you can imagine, this culture is not in line with the modern pursuit of healthcare profits but yet nurses stay fighting the good fight. I see these battles play out nearly every day I go to work and while it's usually done professionally these are real battles with jobs on the line.

In a perfect world I think the software industry would have instilled these same virtues- software is just as (or more) capable of causing harm as poor healthcare. Yet we seem to be racing to a dystopian future at record speed courtesy of the tech industry, and our modern egalitarian societies will not survive that transition.
