“The copyright wars are just the beta version of a long coming war on computation … There will be programs that run on general-purpose computers, and peripherals, that will freak even me out. So I can believe that people who advocate for limiting general-purpose computers will find a receptive audience. But just as we saw with the copyright wars, banning certain instructions, protocols or messages will be wholly ineffective as a means of prevention and remedy. As we saw in the copyright wars, all attempts at controlling PCs will converge on rootkits, and all attempts at controlling the Internet will converge on surveillance and censorship. This stuff matters because we’ve spent the last decade sending our best players out to fight what we thought was the final boss at the end of the game, but it turns out it’s just been an end-level guardian. The stakes are only going to get higher.”
