Hey, it’s great to see other people learn Vietnamese! And your feedback is on point. I’m still at the beginning and just built a tool to help me learn basic phrases. I will very much appreciate the feedback! https://envn.app
Hey, author here. Good point! Historically, all sales people are in a way manipulators, and the best of them are those who know human psychology and behavior. This hasn't changed with how we advertise today. But we should be more restrictive with how we handle the data, who can access it and what they can have access to. That's not as much on the advertising industry as it is on regulations around technology, which is only a recent subject for discussion.
