Wonderer, being so pessimistic you should start studying go.

This answer seems to be answered already by developments of the last few years.
Correspondence chess via mail is dying. As soon ICCF and other organizations succeed in building a specialized server, corr. chees via email will die too. The use of computers in corr. chess is not really a problem, as everybody does it. I do not believe in the few idealistic organisations which try to ban computers from email chess - it is simply not possible to control this. One general rule applies here: everything that is possible will be done by mankind.
This is not bad news. Chess programs may be able to compete on top level in classical chess, not yet in corr. chess and I do not think this will happen the first 100 years. But long term strategy will become more important in corr.chess as every patzer will be able to calculate all necessary tactics. Even that is not a loss; pyrotechnics will not be a great risk anymore.
Classical chess is already slowly getting strangled by FIDE with all the accelerations of time control. I predict that in the not so far future classical chess will cease to exist as all interest will be lost - due to FIDE policy, quarrels between the top-GM's and the unavoidable possibilities of cheating. Compare classical chess on internet - it is hardly interesting.
Blitz and speed chess will survive. With these short time controls using technology is not so attractive as it simply takes too much time.
