Porn will not be filtered, only illegal sites. These are usually filtered out by search engines and account for only 30% of sites that will be blocked. The responsibility should be with parents. The system will be open to abuse so giving parents the freedom to allow their child unfettered access to a computer thinking it is free of harmful images will be irresponsible. In other words the child will still require supervision. In other words a waste of money and open to abuse by government or self interested parties. Also it can be optional so that people without children are not treated as one.
