The disappearance of AM broadcasters

Many AM broadcasters are closing down. 

In 10 years' time the MW and LW broadcast bands may be empty of AM stations. This is a great pity as many of us came into RF via simple MW and LW crystal sets. These are easy to make.

Many AM shortwave broadcasters are also closing down as many now prefer to access these stations via the internet. This is also cheaper.

In 20 years' time I wonder what MF and HF will sound like? I suppose much of this spectrum will be kept by the military "just in case" it is ever needed if the satellites were jammed or destroyed.

It seems the shortwaves will largely be abandoned. In this case, I do hope amateurs (or licence free services) are granted access to a wider array of frequencies. Not that I can see it ever happening, but wouldn't it be great if we were granted access to all of HF at low power on a non-interference basis?
