Not really, as I gave the example of the fingerprinting software
which, by compression, enables uploading on low-bandwidth mobile
telephones. This might serve as an analogue to a language based
compression scheme, as fingerprints contains massive information, but
only a small part is needed for identification:
So analyzing language structure may (or may not) give good
compressions. The use of Unicode code point would then just be the
start of it. But because of the higher bandwidths available, one
should think carefully over the applications intended before getting
started, as it might not be always worth the effort:
The WiMAX <http://en.wikipedia.org/wiki/WiMAX> now installed to cover
the province Södermanland (Sörmland) south of Stockholm will give an
aerial bandwidth of 1 Mb/s (and already installed in some other
places around the world), though the standard can give higher rates.
The prediction for cable bandwidths is that within 10-15 years, 1 Gb/
s will be the worldwide standard in homes, and my network provider
has internally already installed one on 10 Gb/s.
And in 1993, or so I recall, the fastest experimental optical cable
had bandwidth of 1-10 Tb/s on one color only; the optical cable upper
limit should be much higher now. So it seems that there is room for
Moore's law <http://en.wikipedia.org/wiki/Moore%27s_Law> to hold up
for a couple of decades yet to come also in bandwidths.
Even at the lower bandwidth of 1 Gb/s, one can download say at least
100 books per second. How many books are you going to read? :-) - One
of the fastest human readers is he who stood model for the "Rainman"
movie, who can read, and memorize, an encyclopedia in about twenty
minutes (by only reading the parts new from the earlier edition).
