Not that the topic has come up recently. If language exists, then speakers of language exist etc. I assume that many thinkers have contributed to this result. Something which grates on ones nerves. Wittgenstein had and wanted no control over language games.
Radical skepticism is a language game.
Each of us is free to decide for himself or herself. It's the sharedness of meaning that enables us to use words to communicate with one another. The first occasion on which a new word is spoken, no sharedness yet exists. But listeners figured out an effective use for the new word from its context. A new shared, customary use began.
