I think in 10/20 years from now, access to the Internet will be allowed only upon personal identification. Every website will be allowed to ask about your identity upon serving any content. Thats the only way I see this is going. The internet as it is right now does not have a future if majority of traffic will be done by agents. Thus, the cost of that traffic will have to be put on the users and since displaying ads doesnt make sense to agents, a paid access will be introduced (which is what cloudflare is slowly doing)
