I'm not sure it's that fringe. Popular addages such as 'language is a vehicle for thought' and 'the pen is mightier than the sword' reveal that language is sometimes implied to be tool-like, with many of our unspoken acts carrying linguistic meaning (e.g. ghosting, not answering a call, sign language, gesturing, nodding, etc.).
Even tools present us a certain 'language', talking to us via beeps, blinks and buzzes, and are having increasingly interesting discussions amongst themselves (e.g. subreddit simulator, agent based modeling). Recent philosophers of technology as Mark Coeckelbergh present a comprehensive argument for why we need to move away from the tool/language barrier [0], and has been part in informing the EC Expert Group on AI [1].
