It can become really addictive. That loop of having an idea and watching it come to life. A friend and I jokingly refer to it as cyberpsychosis. Because when you code by hand, eventually your brain gets tired and you have to stop. But Claude never gets tired, so you can sort of push yourself past what’s reasonable and spend a wild number of hours prompting for new changes. Instead of a healthy dopamine cycle, it feels more like the inexhaustible random reward cycle of gambling.
