Thank you for preparing me for adulthood

For every 1 new scientist you get because of the current school system you have a thousand others who don't give a shit about the mitochondria.

You have to know a little bit of everything in order to choose to refine a specific area of knowledge when you enter college. That's why we learn 'useless' things. You're probably unable to understand that because you chose to become unemployed or something.

You have no argument and result to insult. How fitting. I have chosen a career path and have been sticking to said career path for 2 years now. I'm enrolled in tech school starting this fall for welding technology. I have a plan.

You couldn't have chosen that career path if schools decided to only teach practical skills. You say that learning about a mitochondria is useless, and for many jobs it is. For many other jobs, math is useless. And for others, writing is useless. If you're going to think narrowly and say that we shouldn't teach useless bullshit in school, you'll soon find that everyone will have no preliminary knowledge that will help them understand the underlying concepts of their preferred career path. Thus, the knowledge that you deem useless is actually important. Just because it doesn't specificall help you doesn't mean it doesn't help others.
