This is so true ,because like in 2022 knowledge is mostly what rule this world not the president. One example , during covid the pople that were mostly listened to were the doctors, scientist and any health officials. The president gave a thumbs up for the plans to follow through but without the healthcare officials things could've gotten way worse than it was. one more example , I there is a shortage of clean water, chemist would be very needy because there is a way to purify dirty water, some companies are innovating on that matter, making it possible to drink a dirty water clean.
