Cuddle puddle!

Not quite an idiom, but one of the senior managers at work keeps talking about Moore’s Law in the context of AI stuff like it’s some kind of fundamental law of the universe that any given technology will double in capability every 2 years

1. Moore observed that transistor density in microprocessors had historically been doubling every 18 months, and this trend more or less continued for a decade or so after he noted it
2. Density has nothing to do with the capability of technology that uses those microprocessors. The performance of the chips roughly doubled every couple of years, but there was a lot more going on with that than just transistor density
3. Moore’s law hasn’t held for at least the last decade
