Sadly, this misinformation can stick and become part of the person. Misinformation can sometimes be difficult to erase especially when we've become top members in the Bitcoin community.
As someone who feels like enough time has passed before I got involved with Bitcoin, one thing I've learned from this forum is to be always ready to research, but aside being ready to research you have to be ready to unlearn a lot of things. I think this rule is a general rule in life. Some things you might believe to be correct might be wrong and when you find out that your view is wrong, be ready to change and learn the correct view.
Some things may be correct before, but not right now or they may be wrong in the past but correct now, that is the dynamism of technology.
We have to have an open mind in other to grow.
