No. There is a difference between an appropriate and one harmful use of technology. Sometimes an ice-cream feels just right, but...
Of course, you could assert the building of the pyramids was harmful to the slaves.
First point - absolutely. Ice cream, without a doubt, is delicious, and I find that eating it while running a fever or having a toothache is most relaxing. I barely eat it though, maybe 2-3 times in the summer. However, it's quite obvious that most people like to have their ice cream and eat it too; too often.
Second point - absolutely, but that sounds like some typical college pseudo-intellectual trying to sling mud upon the great architectural wonder that is the great pyramids. Sure, people died building it, but if I were to be working as a slave in that time, then if I was transported to Egypt today to see what all of the hard work I and others put into it, and that it is still standing today, I would feel a sense of overwhelming pride. (BUT PEOPLE SUFFERED AND DIED AND ITS WRONG TO LET THEM DIE EVEN IF WHAT THEY BUILT STANDS THE TEST OF TIME! I'm gonna go read some pitchfork stuff and listen to Iron and Wine)
