The feds seem to want to replace private Ham operators with federally controlled Firstnet. Not just creating improvements on emergency communication, an alternative to Ham, but to make regulatory changes that make Ham less practical...according to SHTF groups, California’s going after repeaters is one such move.
A couple links on FirstNet:

Not sure it’s a replacement for ham radio.
