Not so smart systems

While it has been a long time wish to have smart machines being able to do our jobs that are boring, dangerous, or repetitive. Still we are very far from that. Blogger editor try really hard to understand what I'm typing is text or markup code. For most of the uses it guesses correctly, but when I'm quoting a xml fragment it always mess up switching between HTML and the WYSIWYG, and is really hard try to figuring out what will en in the frontpage. But blogger is not alone there, recently I've to edit an entry in a Wordpress Blog and I've being greeted with the same behaviour. So I ended not trusting whether I edited but what it was being show when the blog is published. But what is worst is that this smart system were replacing or removing some tags.
