Isn't the idea of building the "next big app" itself based on the same kind of get-rich-quick mindset those schemes are exploiting?
Only except for the "nomad lifestyle" or "selling courses", etc, it's supposed to happen by coding in a dingy apartment. But it's equally unlikely, and too starry-eyed, the tech nerd version of the kind of dream the stereotypical bus-arriving Midwestern teenagers had of "becoming famous in Los Angeles".
How about merely building a business? Think small indie developer or Basecamp at best, vs Facebook and Amazon.
