 \section{The Joy of Commodore 64}
 
-The first computer I ever owned (and thus could use whenever I wanted to, provided it did not annoy the adults in the house) was a Commodore-64. (And yes, my use of this machine seemed to bug adults no end, and I have no idea why. I guess the same adults who thought it was a waste of time playing video games simply thought that a computer is another, more expensive type of video game. The lesson I learned here is to try to get some knowledge before you jump to criticism.) The ``64'' stood for 64 kilobytes, which was the amount of memory it had. If you've never heard of a kilobyte before, and are wondering how many gigabytes that is, it's time for some math, and also introductory computer science.

 Anyway, if I did take a computer class with Mr. Dick, it was a very pale experience compared to my seventh grade experience,\footnote{See the first issue of this zine.} because I don't remember it at all. No doubt there was a curriculum\footnote{Not a bad thing when well done, but years of  teaching experience have proven to me that most curricula are largely designed to take any and all fun out of learning, to say nothing of teaching.} for the class, complete with quizzes, assignments, tests, and long lists of vocabulary to memorize. It would have been completely dreadful and I would have hated it, and would have naturally forced all remnants of it from my memory, so that I would have room for terrible memories of terrible jobs.

 It saddens me that we are now at a price point where technology should be able to transform the lives of millions of people, and free them from the situation they are in now. I know a lot of people say that kids are so much more comfortable with technology now, but this really isn't a great thing. When I was a kid, you used technology to change your life. There wasn't a lot of technology, so it basically boiled down to learning how to use an extremely slow computer to do tasks you'd rather not do, using a VCR to record shows so that you could watch them at a later time, and duplicating cassettes and creating mix-tapes. As I grew into young adulthood and started teaching, I saw more and more how kids could use computers to do a lot of that. Mix-tapes were replaced by mix-CDs. You could manipulate technology to improve your life, and when you were done, you shut if off and called it a day.
 
-Now it's the other way around: technology manipulates you and you \textbf{can't} shut it off. Websites (I'm thinking of Amazon here, as they are the best at it, but plenty of other websites do this as well) now \textit{tell} you what you want to buy. You can buy things on subscription so that you don't have to think any more.\footnote{It can be devilishly tricky to actually unsubscribe from some of these things, to the point where it's easier just to absorb the expense (we can always get the kids vaccinated \textit{next} year) and just decide that this is how you live now.} Streaming services control what you watch or listen to. No longer can you just walk into a record store or a video store and get what you actually want. People have become addicted to their phones in a way I'd never imagined possible. (If you are ahead of me at a red light, and the light turns green, but you don't go because you don't notice that the light is now green because you're looking at your phone, believe me—I \textit{will} let you know that the light is now green and you can proceed through the intersection. Believe me, you will \textit{know}.)

 What strikes me most about some of the videos in the the playlist I've linked above is that the emphasis on using technology is always that it will free up our time to spend time improving ourselves and relaxing. But do any of us really have more spare time as a result of technology today? (I would like to think that as a species we are intelligent enough to do that, but the fact there there is a patch of plastic the size of Texas floating around in the middle of the Pacific Ocean tells me otherwise. "Out of sight, out of mind" is meant to be a warning, not permission to shift blame.)

 It needn't be that way, however. If more of us had been able to experience what I experienced in that seventh grade computer class, perhaps our relationship to technology today would be different. Perhaps we would realize that, like the wheel or fire, technology is a tool to help us improve our lives, not to be led around by it. Of course, look at what we've done with both wheels and fire—we are destroying each other and ourselves as well with them. Perhaps we never should have climbed down out of the trees onto the grassy savanna.

Of course, I could simply clone the old HDD onto my new SSD and then swap them out and upgrade, but for reasons that are long, complicated, and very likely boring, I decided this would be as good a time as any to just start with a clean slate.

 The class was extremely inexpensive, but it was rarely ever full, which made me wonder why more people didn't take this class. There are two answers here. First, this was the early 90s and a lot of people didn't even have computers at home, so what would be the point for them? (You don't need a car if you have no place to go.) Second, a lot of people were terribly intimidated by computers, because they thought you had to be really smart to use them. So they self-selected out of something they were perfectly capable of learning because they thought it was too advanced for them.\footnote{People are really afraid of making mistakes and looking stupid, but that's a by-product of our public education industrial complex. You can't learn \textit{anything} without making mistakes. In fact, people who are truly experts about things often point out that they learn as much or more from their mistakes than they do from their successes. But we have turned making mistakes into something to be ashamed of, rather than something which will help us learn and understand things. Fuck that attitude. Go forth and make mistakes. (Just not in the voting booth.)} Let's encourage people to self-select \textit{in}, rather than out, because once they get here they'll have a lot of fun. Let's not be gatekeepers. 
 
-Fourth, it implies that there is a hierarchy, which I hate. There are many ways in. Because math is so strongly allied to computer science, we tend to view learning about computers as hierarchical as well.\footnote{I think this is one of the reasons that most people aren't good at math and don't like math. Sure, you need to know \textit{some} algebra to do geometry, but you don't need to be an algebra expert. If you really like geometry, and are encouraged to apply yourself to it, you'll eventually learn all the algebra you need. The same is true of trigonometry and even calculus. You don't need to become an expert in those earlier forms of math; you only have to become good enough at them to move on to the next step. People who write math curricula should take note, but they won't.} But that just isn't the case. I started learning how to write BASIC when I was in sixth grade because that's all that was available to us. But basic BASIC is no different than basic Fortran, or basic Cobol, really. The only difference is that BASIC is fairly limited in scope, which was, sadly, all that was deemed appropriate for kids. It's like giving kids little fake plastic tools when they really want to build something.
