BREAKING: Apple just proved AI "reasoning" models like Claude, DeepSeek-R1, and o3-mini don't actually reason at all. They just memorize patterns really well. Here's what Apple discovered: (hint: we're not as close to AGI as the hype suggests)
Se está creando una deuda enorme que alguien va a tener que reparar, y sobre todo pagar, en cuanto a la calidad de los productos de Software hechos los últimos años.
