Yeah, at times I like to think so but I've had so many humbling experiences that I'd wait a little longer before making that declaration.

I had once worked with a senior colleague who would run process traces on the live Oracle database and uncover bugs in Oracle's code. I am at the level where I can find bugs in open source code bases about which I've no idea but not where I can find bugs only with the binary.

Then again, I see so many comments on HN about which I've no idea and which still seem relevant to what I do.

So, you see where I am right now.
