Imagine studying for 3 years
Study 3 more for a PhD. Work at a lab and then work as an intern for miserable pay. Spend years studying and becoming an expert in your field. Test problems and find a never before seen perspective of solving it. Clear peer reviews and increase the overall understanding of the world for your species.
