[molsno]

the most fucked up thing is that my bachelor's degree in computer science doesn't mean a damn thing to any company that's looking for employees because they don't see that as valid experience (even when the positions they're hiring for are entry level). as part of my degree, I had to learn programming languages for individual class projects that only lasted a few weeks. I had to learn data structures, algorithms, operating systems, systems programming, computer networking, and so much more. and I graduated! that means I'm capable of doing all of those things and learning new things incredibly quickly!

but the fact is that they don't want to do any training, they don't want there to be even a single minute where you're adjusting to the company or getting the hang of whatever tech stack they want you to learn. they want you to come in on day 1 and start writing perfect code for them. if you don't already have 2 years of on the job experience working with react.js or postgresql or kubernetes or whatever other specific tech they use, you're worthless to them.

and this is all just a product of capitalism. capitalism is not the most efficient system for accomplishing goals or solving problems, which is what computer science is all about. rather, it's all about generating the most amount of profit for shareholders in the shortest amount of time. I have no doubt that under communism, an economic system that actually prioritizes solving problems to improve people's lives, I would actually be able to put my skills to good use, and that's on top of the fact that I wouldn't NEED to sell my labor just to survive. capitalism makes my passion for programming feel like a miserable chore, because not only do I need to do it just to survive, but I know that every line of code I write is, more likely than not, making people's lives worse.
