But why let the definition of the term "10x" be hijacked by the kind of people you describe? We still need a way to succinctly describe engineers who are an order of magnitude more effective than average. Can't we let "10x" continue to mean what it's always meant, and agree on a new term for toxic team members?
"So I'm going to be sitting in class for 40 hours a week?"
"No. That would be terribly boring and ineffective. You will spend a little time every day learning through curated tutorials and books, and a lot of the time practicing what you learn. You'll work in pairs and small groups on an exciting integrated curriculum. Your brain will be buzzing as you solve problems, tackle challenges, and build applications until you're confident in your mastery of the skills. If you have an idea for a web app you want to build, then definitely bring it. Also it's important to note that even though class is 40 hours per week, you'll be working more like 70-100 hours per week!"
P.S.- I also attended Dev Bootcamp (with feministy, as it happens). I'd say 70-100 hours per week was accurate for my cohort, although this varies significantly depending on a student's programming background.
