You know how we’ve been talking for a while about how many problems in pre-1990s SF could be fixed by having a mobile phone?
The thing I’m noticing now is how so much early 21C SF ignores the possibility of “just text me a photo of what you see.”
(I was doing IT work when phones with cameras became the norm, and “dude, just send me a photo of the patch panel” etc. quickly became indispensible—but it’s not something I’d ever imagined doing before that tech landed...)
