Matthew Continetti writes: As a conservative, I am skeptical of new things. This "technology," for example. I don't own a Kindle. I deleted my Facebook account over a decade ago. It took me years to adopt Twitter, which I did under duress and to my unending regret. I do not play games on my phone, or really do anything on my phone other than email, text, and make calls. I want to restrain and even break up the tech giants, not for economic reasons so much as for political ones. They are growing too concentrated and too powerful. Such amalgamations trigger my populist-republican sensibilities.
