Chaim, answering briefly for Same reason.. as gemora mentions, there is a difference between a professional skill and a business. Businesses come and go and create a lot of opportunities for aveiros. If people are afraid of seeing inappropriately dressed people, what about being locked in an inappropriate business relationship? What about businesses where everyone else hires cheap illegals or underpays taxes, you’ll have to be competitive?
I am very much enjoying intersection of high tech and business, but I mostly value the business part for freedom from annoying bosses. I think any profession where you can run an honest small business is good.
I am not a navi to say which jobs will be good in the future, I work in data analysis and machine learning before ai became cool (again), and while there is hype, there are a lot of real products also
