As Internet turns 40, barriers threaten its growth

As Internet turns 40, barriers threaten its growth...

A variety of factors are to blame. Spam and hacking attacks force network operators to erect security firewalls. Authoritarian regimes block access to many sites and services within their borders.

I believe deep packet inspection (DPI) and better network monitoring can help cut down the spamming, hacking and malware. Also helpful that many Internet Service Providers (ISP's) get it, and offer free virus protection/firewall/etc.
