Totally agree. Many of the first Portuguese and Spanish explorers didn't even know if they would ever come back. They were leaving home to go to distant lands at a time where people still believed in monsters, witches and mermaids.
Every time I read about this type of stories, where they show a small example of how our minds can be "tricked" by such simple tricks or stimuli, I always get afraid about all the other more important situations where this might be happening but we are not aware of it (choosing a career, deciding to get married to someone, etc)
I'm always afraid of investing a lot of time into this type of frameworks and then having the rug pulled from under me. Most of the time I spent learning angular ended up being a waste of time and I'm still scarred from then.
