I don’t think I missed anything. But maybe my post was not very clear?

The post I was responding to clearly meant “like smartphones replaced […] laptops,” which is to say, they don’t think AR glasses will replace smartphones (because smartphones didn’t completely replace laptops). I get that.

Then I pointed out that smartphones did more-or-less replace a number of other electronic devices. And there are some reasons they didn’t fully replace laptops. Then I went on to think about the niches that could exist should AR glasses become a major thing.

> which is to say, they don’t think AR glasses will replace smartphones (because smartphones didn’t completely replace laptops). I get that.

I actually read it as "it will be a replacement in some ways, but also very much not be a replacement in many other ways"
