^Dude, do you think we aren't aware of that billions of dollars boondoggle ITER?
I think the major misconception here is with the term "nanotechnology". The term implies the science fiction realization of the technology in being nanomachines. The reality is that most of the advances in nanotechnology has only been in materials, not machines. Nanomachine technology has not advanced that much at all. Like fusion, it's perpetually 20 years in the future. Until some real breakthroughs appear in the "machine" field the so called singularity is just a fantasy. Even in the materials field nanotechnology has had problems. How many years have researchers spent trying to mass produce carbon nanotube materials?
Materials technology now, but considering the industry started from basically 0 to now a a $2 billion industry, its happened quite fast since Engines of Creation...not only that, carbon nanotubes are one of the greatest areas of recent breakthroughs. I could literally posts dozens of links on the subject so here's just a taste.
At one time fusion was at a standstill, now after recent breakthroughs and the groundbreaking for the test reactor, its moving forward again.
