Some technology makes me more productive (refrigerators, text editors, bicycles, vaccines), and some makes me less (Flash games, irc, hacker news). Others have a mixed effect (cell phones, books). Technology takes many forms, and it's hard to generalize about them all in any sound way.
If one wants to start regulating parts of technology, they must ask the question of whether the expected gains from said regulation would outweigh the costs. With narcotics, its easy: addiction is very expensive, especially for the addicts and productive and non-productive uses are generally easy to tell apart (medical use of morphine v. junkies for example). OTOH, technology is difficult to separate and the side-effects from flash games, irc, et al. are not that significant.
My filter for what made me more or less productive (or an unclear mix) was whether it tended to distract me / take up my time. Spending time on irc when I meant to be working on my programming projects doesn't give me the shakes, but it's still burns up the finite amount of time I have.
Also, I was never suggesting regulation. I don't know where that came from...
