Honestly, I believe this is self-evident, but I'm curious to hear you argue against this.
EDIT: To be clear, I don't intend to deny there are other drivers, but I believe they are rather minor in comparison.
Well, what's the mechanism? The immediate cause of most legislative change- that is, legislation that isn't just fussing around existing laws, or standard partisan back-and-forth- is political change, that is, change in the political outlook and expectations of voters, and it would seem to most observers that the immediate cause of political change is social, cultural and economic change, at least as often as technological change. So the argument is that social, cultural and economic change is always, ultimately, technological, and that is a very big claim.
For example, recent moves in favour of LGBT rights do not seem to have a self-evidently technological cause; yes, the internet and other technologies have helped open public minds, but that's as a means, not a cause, and most of this legislation has a clear origin in LGBT activism dating back to when personal internet access was limited to a few students and academics, if not earlier.
The root problem is that technology does not invent itself. People invent it, in accordance with their own needs or wants, and those needs and wants are shaped by their cultural, social and economic context. It's not enough for the technological potential for a printing press to exist, for example, if a society doesn't want to invent it. The Near East had the potential to develop a sophisticated iron-working culture for hundred of years before it actually did so, because the cultural, social and economic conditions did not exist to make iron preferable to bronze.
Looping back to the topic, it also seems that technological determinism sits uneasily alongside representative democracy, at least as it now exists. Politicians are not particularly technological adept, or, at least, they aren't selected on the basis of that adeptness. Some are seeming technological illiterates; "it's a series of tubes", etc. You've pointed out that most voters don't have the time to investigate every piece of legislation out forward- but what is time without understanding? What good would an entire set of people dedicated to fussing over legislative minutiae be- as if politicians spent most of their time legislating rather than simply politicking- if they did not understand the significance of the legislation in regards to technology. The implication would be, if not the abolition of representative government, then it's restructuring along very different lines, either corporatist or syndicalist, depending on your political preferences.
