Hi Bill, Yes, we should be. Unfortunately, most scientists are NOT aware that units like angstroms are deprecated. I only know because I read the SI brochure, at your suggestion in fact.
There has been a slow and steady trend in physics education to move away from cgs to SI. Most freshmen-level physics and chemistry textbooks have a page or two in the introduction about SI. However, each specific field has its own preferred units, and the journals don't seem to be moving toward SI. It seems like every field has its peculiarities. For example, high energy physicists measure both mass and energy in electron volts (eV). Sometimes using non-SI units is not optional. For example, sometimes converting to SI would lose precision. As a historical example, there was a time when the distance to Jupiter could be measured precisely in AUs, but the length of 1 AU in meters was in fact not yet precisely measured.
