There are opposite developments, providing a broader spectrum, where
in some circumstances it is less important with compression in view
of more computer data space and higher bit-rates, whereas, in other
circumstances, even better compression can be used in view of higher
processing power.

I think Apple has a new lossless compression for their music computer
products, which could mean that they sense that compression becomes
less important for music files. The compression formats have the
problem of loosing data, so therefore, when computer data space
becomes more available, there is movement towards various "raw" data
formats.

This is mainly for larger sized movies. So if compression becomes
less important in the future, that is down the road for movies.
If I should tie this something relating to Unicode: compression is
not going to be important if you type your manuscripts by hand. For
intermediate sizes, standard binary compression might do. But if you
have a large library, then it may be very important have a very good
compression method, not giving only the couple of times, like the
standard binary compression methods.
