It is just a clever restatement of "If all you have is a hammer, everything look like a nail."

Doctor: No problem, I've got a screw-driver.

I had a love-hate relationship with my 150-in-1. I could build oscillators that generated tones, and change the tones, and what not. But it never really explained why/how it worked. It had PNP and NPN transistors
I eventually moved up to a 250-in-1 kit with digital logic chips. That was cool! You could understand how a flip flop worked by tracing the logic 0's and 1's. Although analog circuits came before digital ones, digital ones are easier to grok, which leads to more learning. At least, in my case it did.

he imported a fly
