Today, I got messages from 3 different devs at 3 different large tech companies (1,000+ devs each). "tokenmaxxing" is happening inside all of them. Why? Because all of them measure either token usage, or surface metrics like DX's TrueThroughput that reward complex code!

Now, the key question isn’t whether Skills exist or whether they’re well-designed. The question is this: do they offer something we can’t already achieve with

Are you able to review all the code your AI agent writes? There's an equally efficient way by adopting an AI Native-oriented approach.

Este paper del MIT demuestra que el uso continuado de ChatGPT y otras LLM provoca un considerable descenso en la capacidad intelectual. La IA te jode el cerebro. Es así. Por eso hay que prohibirla. Como mínimo, en toda la comunidad educativa y en todo el sector público.
