Science is literally the path towards understanding of the world around us through hypothesis, experimentation and study. That's definitionally being open minded and curious.
Your statements imply that we can't trust scientists because of their "authority" and that they just use that position as scientists to nefariously control you?
Why should anyone trust you? "Curiosity", having an "open mind" and "a nearly full-time job for about 10 years" aren't credentials anyone with critical thinking would recognize as reliable.
Whether you like it or not, scientists and doctors have to go through many years of rigorous study and full-time practice for their specific fields and are constantly challenged by their peers in their work place and in academia. That's a more reliable (tho not perfect) set of credentials.
Scientists are intellectually adversarial to each other by nature because all ideas must be challenged (eg peer review) in order for those ideas to become consensus. Science is constantly in a state of change and evolution as incorrect conclusions ideas are abandoned in favor of more correct conclusions, based on new learning.
That's the whole point. Science will get things wrong, it's impossible not to some times, but the global scientific community is constantly seeking to get closer and closer to base "truth" about the world.
Unless you have some other suggestion, I don't see any other way humans can get a clear understanding of the world other than the scientific process and I see no less reliable source than the current global scientific consensus.
