I wish I could upvote this twice. I spent a long time trying to write a similar comment and eventually deleted it; yours is better. Of course Bitcoin isn't perfect and it's entirely possible that it doesn't stand the test of time+. But people who insist on behaving like it's a joke or a toy when there is a multi-billion dollar economy around it and enormous chunks of pretty smart VC money (not to mention Stripe's investments in the ecosystem--they seem to know a thing or two about exchanging money on the internet) end up looking pretty stupid.

+ I can certainly appreciate the opinion that Bitcoin won't survive in its present form, but I think it's becoming more and more obvious that cryptocurrency in general won't be leaving us any time soon, and I think ignoring Bitcoin's role in that development is extremely foolish.
