Conferences are not training.
You can travel and go to a training course where they deep dive you on a topic for one week. Maybe you are there with a colleague or two, but you are not there with thousands of people, all in one class, all learning a topic and struggling through labs.
This is good because struggling to do a lab with a thousand people would be daunting on a good day.
Conferences are many things (as already gone through) but they are not training, they are learning.
Different audiences, different topics, different opportunities, don’t sign up for one without knowing what you’re looking to get from it.
