Even 10-15 years ago no one used such devices.

I find this to be fundamentally invalid logic.  With this alone there would be no progress.  Ignoring that there wouldn't be Kevlar, there wouldn't be cedar/canvas or even canoes at all. 

Here's a fun exercise.  Try this on your wife.  Tell her that for years women didn't have rights, didn't need rights.  Ergo, they don't need them now.

It's all relative based on when one started.  Look at the Luddites.  They never claim to actually avoid all technology, just the newer stuff introduced since they got started.  The Amish would love zippers if they got started in the 20th century instead of the 16th.  I've never seen anyone refuse to use simple machines, levers/inclined planes/and such.

Things need to be valid on their own right.
