Today is the era of AI. And even long ago Aristotle said, "Whoever wants to answer a question must first formulate it correctly". And he showed that a false premise in a question inevitably leads to a false conclusion. Even with all the possible power of AI. Also, Charles Kettering, a famous American inventor and head of research at General Motors, said: «A problem well stated is a problem half solved.» I am the one who formulates problems for AI correctly. That is because I have 25+ years of experience and expertise in both mobile and web development, networking, leadership, and project management.
