I have upvoted your remarks, not because I agree, but because they are a classic example of head-in-the-sand thinking and should be paraded as such.

As a young developer I was often told "you can't do that" or "stop jumping to solutions" and as a now much, much older and very slightly wiser man I recognise that these were the knee-jerk fears of threatened reactionaries stuck in their ways, not the wise voices of experience that they thought they were.

As someone else implied, the appeal to authority is one of the least credible forms of supporting argument.
