I distinctly remember the first time I saw someone with a cellphone at the beach. It was 1992 on a lovely beach in northern Brazil.
A man was lying peacefully on the sand, eyes closed, sunning himself, his cellphone right beside him. Which was unusual, because in that year cellphones were unusual, at least in the U.S. If you had one back then, it was because you needed it for work.
I remember thinking that this could be terrible or it could be great. Terrible because the man clearly was unable to get away from whatever work and responsibilities were glueing him to that phone. Great because he was able to be at the beach even while he was working.
Today I was looking at my Quest Pro, and thinking that in 5 or 10 years some more advanced version of this will have the form factor of sunglasses. And then, in some form, I will probably see a repeat of exactly the same scene.
A person will be lying on the beach with what look like sunglasses, but which I will know to be functioning smart glasses. And I will be left thinking that this could be terrible or it could be great.
