I have honestly just been using ChatGPT itself. It is devastatingly good for written language learning and I suspect it is only a matter of time before it is that good for verbal needs.
The comment you're replying to is talking about the need to actually speak a language to learn it fully (as opposed to just reading/writing), which could definitely be fulfilled by talking to a smart fridge.
They're not saying that the fridge is able to replace human relationships generally.
I wish they didn't take out the "off the screen" outputs from the previous voice mode. I miss being able to ask it to output an image or codeblock when I wanted to come back to something later.
