I'm stunned... I've already signed up for ML, was thinking crypto, and now this? Some people dream of winning the lottery, I would be happy for a 6 month sabbatical from my full time job to immerse myself in these classes. I've currently taking the AI class and a enjoy it immensely. I feel the my 'bag of programming tools' has grown exponentially with all the stuff I'm learning.
How much time does the course use up? I expect everyone is different - so it's a personal question of your time. Are there homework assignments or exercises? How are the practical aspects handled for example with learning a programming language?
