A post from Bret Horsting argues that specialized knowledge in specific fields has always been the strongest moat for tech companies, not technology itself. The piece generated significant discussion on Hacker News with 177 points and 113 comments.

The discussion underscores a broader shift in tech thinking: commoditized technology and capital are widely available, but specialized expertise remains scarce and difficult to acquire.
