I believe that was the entire point of the comparison. Smartphones replaces SOME use cases of laptops in the same way ubiquitous smart glasses could replaces SOME use cases of smartphones.
If you are afraid of technology, Android or iPadOS is lightyears ahead of Windows or MacOS.
It's more than enough to handle paying bills, applying for jobs, etc. Hell, a Bluetooth keyboard and a bit of grit + GitHub CodeSpaces and you can write develop applications.
You can also cast your screen to a TV or on a handful of phones use USB c to HDMI.
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.
It is hard to say when the peak of laptops in circulation was, right? Because simultaneously the tech has been maturing (longer product lifetimes) and smartphones have taken some laptop niches.
I’m not even clear on what we’re measuring when we say “replace.” Every non-technical person I know has a laptop, but uses it on maybe a weekly basis (instead of daily, for smartphones).
Laptops, of course, have the much bigger screen and keyboard, not really replicated by smartphones. They have use-cases that smartphone can’t cover well for hardware reasons. So they’ve stuck around (in a notably diminished form).
If good AR glasses become a thing… I dunno, they could easily replace monitors generally, right? Then a laptop just becomes a keyboard. That’s a hardware function that seems necessary.
What niche is left for the smartphone?
