It's down to the market. There aren't that many beginner or mid-level jobs in the field and there is a big oversupply of candidates. I wouldn't recommend data science or machine learning to people who are changing career direction or need to invest a lot of time/money/effort to catch up with all the theory. Not that it's impossible, just very hard. It's also getting more and more gatekept over time with increasing requirements for advanced degrees.
