supplemental tools for my lack of higher education

Chatbots might seem smart, inteligent and educated, as they are using fancy and complicated words, but it’s a lie. They don’t know what they are talking about, they will be sycophantic to you and agree with every falsehood that it might came across.

You can pursue higher education without paying a dime. You won’t get fancy paper, but you can build an expertise yourself. There are plenty of textbooks out there. openstax.org is great resource to get high quality textbooks. I have watched lectures on youtube to get an education that wasn’t available for me at the time. No one will be able to take that knowledge from you.
