This is what always confused me about VC AI enthusiasm. Their moat is the capital. As AI improves, it destroys their moat. And yet, they are stoked to invest in it, the architects of their own demise.
If AI gets good enough to replace all human labor then actual physical moats to keep the hungry, rioting replaced humans away will be the most important moats.
If AI renders human labor a cheap commodity (say you can orchestrate a bunch of agents to develop + market a Windows competitor for $1000 of compute), what used to be "Satya + his army vs. you" now becomes mostly a 1:1 fair fight, which favors the startup.
