Strongly disagree with this. I know 50 people that think they can learn to do Data or something with an Udemy class and end up doing nothing.

I think the negative picture painted by the author masks that the company is placing 50% of graduates which mostly paid nothing for the education they received. Lambda is not high quality education, but its super cheap and higher quality than just reading a Knuth Book, or Skenna's algo book which has no completion rate.

Sounds like you know unsuccessful people. I know plenty of developers who became front-end or dev ops from their own studies. It's not too hard to learn SQL or data visualization. The majority of questions can be answered via stackoverflow or slack communities. You don't need to know everything to land a entry-level job, you just need to prove you know how to problem solve.

Either way, you are not becoming a true machine learning researcher via self-study nor a bootcamp. You will need at least a master's in CS/Math/Stats to land those roles. A bootcamp is neither the lowest cost to a softwaredev career nor is it the a career effective maximizing choice.
