A while back, I was thinking about how things have changed in the Shadowrun setting, accommodating newly-developed technologies as well as taking things we haven't yet worked out. This game has always done this, even when it first started -- it had the idea of the direct neural interface and VR when most people (save a certain author) hadn't even thought about it. I was thinking about one aspect that drastically changed recently: the reintegration of wireless tech.
More specifically, I was thinking about this question: Why would wireless have vanished completely by the 2050s? This might have been answered in a recent book (I don't have Unwired), but here's my theory:
Even factoring in the divergence in the timeline around 1990, technology would still progress at an explosive rate. By the 2020s, we'd have global Internet coverage with few or no dead-spots; cheap high-speed Internet access (with, naturally, insanely fast speeds for those with money to spend); devices easily able to talk with each other via wireless link.
Then comes the Crash of '29, with the nastiest computer virus ever running rampant. All this is familiar to anyone who's on this board, so I don't need to reiterate the effects that have been documented.
But here's one that explains why wires came back.
The Crash Virus required three things to propagate: a storage media, some form of OS to enable it to operate, and a way to reach other systems. Consider how many devices today meet these requirements. Naturally, computers and laptops fit, but so do most cellular phones (especially smart-phones), wireless routers, GPS devices, modern game consoles (and even some hand-held types), some of the fancier remote controls, even little 'toy' gadgets that interact with each other.
Consider this: The Crash Virus gets itself planted in someone's netbook. Rather than just immediately start trashing the place, it sits dormant, monitoring the owner's communication hardware (typically, a wireless receiver). The moment it finds a network that's within its range, it connects, plows through any security measures, and plants itself there too. All it takes is one infected computer approaching a Starbucks, and every laptop and smartphone within range is infected within seconds.
Any location offering "Free Wi-Fi" would become a breeding ground for this virus. And that's just to reach the wireless devices within its range; if this area has an active Internet connection, well, it just went global in that 3.8 seconds.
In the year and a half (or so) that Echo Mirage needed to track down and wipe out the virus, there were other steps taken to limit its mobility -- specifically, tearing down the entire 802.11 protocol. Anything using wireless technology -- Bluetooth, WiFi, whatever -- had to be recalled or had to have "mandatory firmware updates" that disabled wireless communication permanently. Considering that the virus tended to burn out hardware as it finished its job in a particular device, this didn't require a lot of work; by the time this process went full-time, many of the targeted items were already rendered useless.
So, with everything having to go back to a direct wired connection, fiberoptics made a reemergence, and everyone grew accustomed to having to plug in their devices to have them talk to each other. This would become the standard state of affairs until the late '50s and Crash 2.0 gave people an incentive to rebuild (again) the Matrix and how it worked.
What do you think? (If any of this has been backed up and/or shot down in any of the books, please provide a reference if you can.)
