Author is projecting. Replaced "me" with "people" in writing this. Considered himself smart; tried to wrap head around Bitcoin, but lacks math/cs/finance background, and or curiosity to dig below surface level hype or read blockchain-y things beyond what's written by other lazy journalists ...? (now I'm projecting). Doesn't 'get it'. Plenty of people understand Bitcoin. Go read the whitepaper.
However, at this point I can only see it as a currency. So I can't say if the second point is even applicable here.
Maybe the reference is to the underlying blockchain, the effort required to understand it, and consequently customize it like people did with the older web technologies.
