“Any product that needs a manual to work is broken.”

Simplified Meaning:

When a product isn't easy to use without instructions, it means there's something wrong with its design. Think about how you use a smartphone; you pretty much know how to swipe, tap, and press buttons without a guide because it's designed to be simple and intuitive. If you bought a new kitchen blender, you expect to know how to use it by just looking at it: put ingredients in, press a button, and blend. Imagine, however, if your blender came with a thick book of instructions, and you had to read it just to make a smoothie; that would be overly complicated and frustrating. In real life, the easier something is to use, the quicker people adopt it and the happier they are with it. For example, social media apps succeed because they're easy to figure out and don't need a manual to get started. If you're creating something, make sure it's very user-friendly; otherwise, people might give up on it because it's too hard to understand. In your day-to-day life, if you notice something is really tricky to use or understand, it's often because it wasn't designed well from the start. Focus on simplicity and clarity to make things better and more effective.
