Either "no one" or "Satoshi Nakamoto". Thankfully, Satoshi isn't around anymore, making it currently no one.
This is a good thing, because extremely powerful influencers are a naturally centralising force on decision making. Many people prefer to follow someone they agree with and stop thinking critically when that person says something they otherwise might disagree with if said by someone else.
There are some people that I consider very influential, very clever, and very aligned to my views. People like Andreas Antonopoulos, Saifedean Ammous, many of the core devs, and so on. However when I find myself agreeing with them too much, I often go out of my way to find things I strongly disagree with them on so that I can maintain a healthy level of criticality when they say something else that requires careful examination.
To note: I haven't yet found anyone that I agree 100% with; and I consider that to be very positive. I even probably disagree with Satoshi about a couple of things based on some statements he made, but since he's not around to discuss them and elucidate/clarify his opinions further, I won't say that with certainty. I will say however that I disagree with the interpretation I have of a couple of things that he said.
Very true, and of course it's hard to find anybody you'd agree with on all the things. I think this also goes for pretty much everyone who by design *is* the most influential person in any other given project, like Vitalik for Ethereum, who is also controversial.
