If you really want to blow the minds of younger fans, tell them about photolithography. "You mean he can make computer chips in the red room?" "No, the chemicals are different as are some of the steps. What I am trying to say is that similar concepts are used. Things like the exposure of photosensitive materials to light and using other chemicals to change the properties of exposed areas." "That doesn't make any sense at all. Light can't change chemicals." "Of course it can. That is how photosynthesis works." "What do plants have to do with this?" "Very little. I was just using a common example to prove that chemicals can changed by light." "Okay, but plants are different from computer chips and photographs so I still don't see how it's related." (The conversation continues in circles for a bit.) "Look, we used to think about things in very different ways. When your generation and my generation sees stuff coming off of factory line, we have a tendency to think of things being made in mechanical ways. So we're the same in that respect. On the other hand, you see a lot of things being created digitally so you have a greater tendency to think of things being built up from bits in computer memory. My generation saw a lot of things being made by carefully controlled chemical reactions, so it is easier for us to imagine things being created that way. Just because I have less exposure to the former doesn't mean that it does not exist. Just because you have less exposure to the latter doesn't mean that it does not exist. The world changes. Get used to it. Heck, have some fun in the process and explore the old ways as well as the up-and-coming ways. It will make your worldview much richer."
