Not if the free market stays as it is no
you should also bear in mind this is an incredibly small poll of only 95 people which doesn't represent the population of the world or even the amount of people using Bitcoin, in fact, it wouldn't surprise me if there were just as many or maybe more women/ethnicities because of the pretty anonymous nature of Bitcoin. If everyone's only identity is an address then how can people judge them on their appearance or gender unless they reveal themselves?
It's not about appearance or judgement, but the early adopter demographics, which consistently seems to be dominated by young guys, usually white with a few Asian guys in the mix.
It's been like that during the Internet boom, the dotcom bubble, and I suspect it'll be like that again during the early stages of bitcoin, i.e. now.
Sure, you can say, "what't the problem. us nerds are just quick to adopt new technologies", but I see several problems with this. (a) I personally think diversity/heterognity almost always beats homogenity, and (b) in 20 years from now, when bitcoin is fully accepted (let's say it is), we will probably have to somehow
correct for this, similar to how we do now with quotas for female CEO/board members (in the EU) or affirmative action at universities ( in the US)
I think it would be kind of preferable if we could get some more people from outside the core group to join our little experiment now. But I admit, I don't think it's very realistic.
