How do you expect a language model to see through propaganda and other large-scale misinformation by power/money with a megaphone?
How do you expect a computer program that can't reliably determine what letter a word starts with to determine objective truth?
I appreciate that you have a passion for the subject, but this tool is fundamentally unable to do what you wish it to do. If your goal is to make money -- keep going forward. Big promises built on lies have made many tech billionaires. If your goal is to combat misinformation you'd be better served by doing it in a different way than relying on a machine.
If you're building this at sixteen you have no limits. Don't take this as discouragement towards building things -- take it as a warning against cybernetic totalism. Make the world a better place not through technology that tells humans how to be or how things are; make the world a better place by building technology that adapts itself it human needs. Maybe even build technology that needs humans more than the humans need the technology.
