That poster is the result of ~70 years of hardcore work and blood and sweat of ~10k+ people on the human mitochondria. That poster alone is worth billions of dollar of research and will likely save billions of lives. And it's just the normal functions of the human mitochondria. One of many organelles in a 'typical' human cell. I'm not aware of any attempts to produce such a thing for something as complicated as the ER or the nucleus.
Our understanding of bio is very much limited. But I want to stress that Bio is complicated much more beyond what anyone thinks it is. There is a good quote to help grok the ocean we are looking into:
Imagine a flashy spaceship lands in your backyard. The door opens and you are invited to investigate everything to see what you can learn. The technology is clearly millions of years beyond what we can make. This is biology.

That said, with higher degrees comes higher wages. And with 'outsider' skill sets comes higher wages. Things like programming, EE, and management-skills will get you a better job in bio. Honestly, most bio people don't have anything past Calculus 1, so if you even have Linear Algebra, you're much ahead of the group, let alone Diff. Eqs. or some real Stats classes.
Granted, these salaries not near SWE jobs, but you're not working on dog-walking-apps, you're working on heart conditions and health issues. The effort, inherently, is compensation to those doing it.
