Funny how usage of the the word moat simply exploded here on HN a few weeks ago.
But this isn't the first gold rush in the tech industry and folks have been talking about moats here forever.
There's an initial peak in 2023 (haven't looked it up, but I'd bet that was when 'OpenAI has no moat' was on the front page for a while), and then it settles down a ways above the previous average. Since December it's been 1.5-2x more frequent than where it settled after that first peak.
