Will the Internet survive?

The phenomenal worldwide popularity and growth of the Internet and Web is under threat from many directions, globally and locally: spam, viruses, denial-of-service-attacks, pornography, paedophile soliciting, fraud and government monitoring and censorship. These threats raise many questions of vital social and economic significance, such as:
Will the Internet’s value be undermined – and its survival
endangered?
What can be done technically, such as in the area of
security?
What can users, households, Internet service providers and
industry do?
Are policy responses required, such as Internet governance
and regulation?
Will the next Internet protocol (IPV6) and other technical
advances help?
Or will the Net become clogged up until there is an
e-traffic gridlock?
