I wrote it to be tongue-in-cheek in a ranting style, but essentially "AI" businesses and the technology underpinning it are not the silver bullet the media and marketing hype has made it out to be. The linked a16z article shows how AI is the same story everywhere - enormous capital to get the data and engineers to automate, but even the "good" AI still gets it wrong much of the time, necessitating endless edge-cases, human intervention, and eventually it's a giant ball of poorly-understand and impossible to maintain pipelines that don't even provide a better result than a few humans with a spreadsheet.
