You're not ready to invest in yourself or just looking for the cheapest way to learn. If that's you, no problem, use our free Learn to Code + AI & Get Hired guide.
You don't think fundamentals matter anymore because AI can do everything for you. Understanding the fundamentals and how things really work will always be important.
You think AI is going to replace you and think there's nothing you can do about it. Well... if you keep wasting time not learning AI tools & skills, you're probably right. Or you embrace them, and 2x your productivity (and probably income too!).
