I was rereading your book Unbounding the Future, and it appears to me that a very useful route to more advanced MNT would be this concept of attaching molecularly precise gripper tips onto SPM heads, and then use that to pick and place molecular parts into the next stage of nanomachinery. What do you think regarding using controlled streams or pulses of electrostatic or electromagnetic waves to start off assembler technology? One criticism I read about this route, is that EM waves would not allow atomic precision, or something like that. Thoughts? Thank you.

There are many. Carbon nitride, boron nitride, corundum, and others. Doctor Drexler: In theory would some form of compressed hydrogen if it could be stabilized, be harder and stronger and stiffer than diamond, like someone was claiming, or not?
