Nope, I don't remember that reality. In mine, many people were excited about it, but plenty of us were as creeped out then as we are now.
Well, okay, if you say so. My perception of their, uh, "fatal mistake" differs somewhat. First time I visited Europe was shortly after Bluetooth earpieces had started to catch on there, but before many people in the States had adopted their use. It was weird to see otherwise competent people gabbing away at (apparently) nobody at all as they strolled on down the street. Took some getting used to, and of course, wireless headsets are fairly ubiquitous and commonplace now, but for a while those early adopters had to put up with some quizzical stares from people who thought they looked ridiculous talking out loud without holding a plastic box up to their ear. Wireless earpieces make all kinds of sense to most people now, and so they've successfully infiltrated the realm of the commonplace.
But Glass is different. A Bluetooth earpiece allows one to talk on the phone without holding the phone up to ones head; the benefit is transparently obvious. Glass does much more. It allows one to access online information without using one's hands. It allows one to enjoy many benefits of augmented reality. Neato. But it also allows someone to record video relatively unobtrusively, without going to the trouble of buying and rigging a spy-camera in one's clothes. And it's never made particularly obvious what the Glass-wearer might be using their Glass for at any given moment. Might be feeding the wearer realtime pickup lines, like some 21st century Cyrano. Might be set for some facial recognition in sensitive situations. Might just be being nosy. Or it might be engaged in nothing at all nefarious.
And then there was the Explorer rollout, where handpicked people were allowed to get hold of the device a full year before anyone else could, for the not-particularly-universally-accessible price of $1500. Lots of people would be envious and resentful, particularly if they wanted a pair for themselves. There was a certain amount of cachet associated with parading around with Glass on your head, and that was inevitably going to trigger further resentment. Was the Sarah Slocum dustup actually surprising to anyone?
It's easy for you to claim that Glass is as "harmless" and "convenient" as Bluetooth, but it's not always obvious (nor is it guaranteed) that Glass wearers could not harm anyone with their Glass, if they chose to.
My kids have had occasion to try out Glass (they know a guy), and they think it's kinda neat. No doubt they'll grow up in a society rife with such things, and they'll roll their eyes right outta their sockets at their weird old Dad who fetishizes mechanical throttle linkages and handwritten notes and landlines, and still won't reopen a damned Facebook account. And they probably won't listen if I try to explain how, at the dawn of the Augmented Reality Era, the pioneers of Glass, the Explorers, were often seen as entitled dweebs who couldn't imagine why anyone would be irritated by them wearing an expensive, exclusive, largely unavailable, and apparently easily abusable camera/computer on the bridges of their noses.
But just as Henry Ford had to convince people they really needed cars, and Zuck had to convince people that their lives really weren't complete if they weren't sharing every last moment of it on social media, Google's gonna have to try to convince people that Augmented Reality is simply so awesomely beneficial that you can't believe you ever got through your day without a wee blinking window to the Net in the corner of your vision all the livelong day.
I'm pretty sure I won't have any trouble resisting that pitch. And though I'm not about to call my kids assholes for thinking Glass is pretty neat, I will have some difficulty taking Glass wearers seriously... possibly for a long time. There's something vaguely self-absorbed about keeping one's interface stuck in one's view as one moves through the outside world... and doing so during a period when very few people have the privilege to do so comes across as somewhat assholish all by itself. Google couldn't really win with a rollout like this.
