Fair enough. But for every bill gates we can find a mark cuban, michael saylor etc who are extremely excited about bitcoin. So I still think it is uninteresting.
First you said "Just because Bill Gates is a billionaire, doesn't mean he knows what he's talking about"
Now that you've learned that most likely he DOES know what he's talking about, you changed your argument to "Other people think other things, so it's uninteresting" (What? WE're not talking about random people here.)
Lets just say it: you already arrived at the conclusion you want, now you're grasping for arguments to support it.
