Hi, John. I too lost a bunch trading options stupily in the 70's.
Regaining your self-confidence is harder than getting the dough
back, I think, though I'm rehabilitating myself.
Regarding "We all know that S/390 rules at the very high end."
What happens when a market segment with margins that support
"lease jets to get the right people to an account having
problems" when it gets uppercut from below by cooperating,
scalable systems which are near-commodities and priced accordingly?
These systems are reality (though not NT at the moment).
They are scalable in small increments which, unlike s/390
clusters, scale essentially linearly.
For instance, Cpq/Tandem systems run all the major stock
exchanges in the world at a fraction of the equivalent
s/390 price and with far greater fault tolerance levels
achievable on an s/390. Capacity can be increased in
small increments.
Mainframes are doomed eventually. True there are corporate IS
cultures and legacy software and supporting applications, etc.,
which will provide geriatric support for the next xx years.
I don't know what xx is, but it's a lifetime of a legacy
market segment. |
