Smart glasses offer AR, AI, and enhanced features, but aren't ready to replace smartphones. While promising, they still face limitations in processing power and battery life, making them a complement rather than a replacement.
No, I don't think we're at the point where smart glasses are really functional. It's difficult to change the comfort and habit of using a phone to a pair of glasses, but as a complement I will be able to use them without any problems.
I don't think we're at a point where smart glasses are going to replace cellphones. Maybe in the next 5 years? Who knows, I'm sure the technology will be there to make smart glasses even better than they already are.
