I think the real issue today is the unpredictability of delays even though computers are overall much faster. When the same action can have such variable response times depending unknowable variables, your brain begins to believe that you're working for the computer and not the other way around. It just changes your relationship with your computer in a subtle yet fundamental way. If you hired a professional cutlery expert to feed you it would be faster but it's no longer mechanical -- they might occasionally get distracted by a text message and 1 in 100 bites are completely missed. Now there's a gatekeeper between you and your meal. When it's working it's way more efficient and awesome, but your brain now understands that your meal isn't really guaranteed anymore. Our relationship with computers is fundamentally different in a way that our subconscious immediately grasps despite being somewhat irrational.
