Chemists aren't that important. I'd replace number 10 with indie game devs
1. Farmers – food is non-negotiable for survival.
2. Doctors – treat trauma, infection, childbirth.
3. Water specialists – clean water prevents mass disease.
4. Engineers – rebuild tools, power, transport.
5. Builders/carpenters – shelter against elements.
6. Mechanics – keep remaining machines running.
7. Security – protect food, people, order.
8. Blacksmiths – forge tools, blades, hardware.
9. Teachers of practical skills – pass knowledge fast.
10. Chemists – medicines, fuels, basic materials.
