The Gettier problem is overrated.

The question is "what is knowledge?", not "do we know that we know p?". And I see no issue with the definition of knowledge as justified, true belief. Now, if I believe p, and you ask me whether I know p, I may say yes. But whether I actually know p will depend on whether my justification is valid (that it really is a justification and a sufficient one) and whether it is true, which has nothing to do with whether anyone knows whether the justification is valid and the belief is true. It's a separate question, and conflating the two questions leads to an infinite regress of skepticism. So the definition of knowledge qua knowledge still stands.

I would also suggest you try to apply your general approach to the very theory you are proposing. I see an opportunity for retorsion arguments.

This issue is fairly significant for me.

I approach it with words using the idea that everyone has the foreknowledge of the Merriam Webster dictionary definition of the words they choose to say in conversation... and something often taken for granted when it shouldn't be.

I know what I mean when I'm explaining things - the definition of the word in context, with some Grammer etc.

What is being interpreted tho? What thoughts come to your mind when I type "Planet Earth" and you read it? Whenever I see the words Planet Earth I recall a memory of an HD DVD BBC Documentary titled "Planet Earth" sitting on the lowest shelf on the endcap display at my local Best Buy - I noticed that many years ago and I've told a few people that, so now it's likely my forever. Lowkey nostalgic almost.

Say I'm having a conversation with a friend that shows a headline about "Planet Earth Be Doomed" how could they ever anticipate my nostalgic correlation with that headline? Am I actually listening if I finish an entire conversation while reliving a childhood trip to best buy?

This only seems like a tangent - knowledge and truth are exactly the same.

I know what I know. I know what I expect you to know. I know what I'm trying to convey and so I use words I know the definition of and feel appropriate in the moment, sometimes I even try my best.

I never know how someone will react/respond/understand.
