I have a rayban meta and ask it various questions on STEM (ex: what is entropic gravity). Its responses are brief but accurate. YMMV but it seems fine. However for detailed discussion I use the ChatGPT voice mode. The glasses are a pretty capable Bluetooth headset end to end. I often use it for this - a good head phone that doesn’t stuff up my ears. The built in AI I’ll use for things like “remember what level of the parking garage I am on” where it snaps a photo of the level number and I can ask later.
