Technology Isolation?

I was pretty surprised by the Neil Postman Article - Some New Gods That Fail. In fact, I was kind of offended by it. The one argument that I had the biggest problem with was when he claimed that computers create an environment where individuals are isolated, and therefore they should not be heavily depended on in a classroom where social learning should be occurring. While I agree that learning is effective among peers and in groups, computers promote exactly that kind of education.
We have been reading several articles about blogs connecting students to people in other nations, and even to their own communities. Some teachers have set up blogs exclusively for classroom use so students can share ideas about homework, readings, or just a place for free and open dialogue. Computers in no way create an environment where children learn in isolation!!
In addition, Postman also makes the claim that teaching technology education is a waste of time in schools. He argues that "approximately 35 million people have already learned how to use computers without the benefit of school instruction." Even if that is the case, technology and computers are going to be more and more prevalent in our society, so isn't it only fair that prepare students to face that? Also, just because this statistic claims that people are learning to use the computer on their own, it does not indicate what they are learning to use it for. Schools need to teach students how to use word processing and spreadsheet programs, and other educationally related tools that aren't "picked up" when surfing the internet.
While I agree that computers and technology should not be the only media students learn through, we have to face the reality that we live in a society that is technologically based. It is only fair to students that we as teachers prepare them for this world. Most kids these days are very tech savvy - using technologies that they use daily and are familiar with is a great way to engage them!!
