I hate to be a wet blanket, but the frustrations of software
engineers with poorly engineered software are NOT TYPICAL of
the current market for most packaged software or software
for the commerial market.  Unless one recognizes this, it
is bound to lead to wasted resources.

Software directed toward the mass market is sold based on
(often misleading) advertising.  What sells products is the
promise of new features or functionallity.  Typically, nothing
is said about reliability.  Reliability is something the buyer
only discovers after paying their money.  Because it takes
time to learn how to use the software beyond tutorials and simple
uses, the buyer generally doesn't discover it's faults until
well after the product can be returned for a refund.

In addition, most users restart their computers and
applications often enough that the effects of memory corruption
are minimized.  Most users, who don't understand that reliable
software is possible, believe that periodic "crashes" are
something they have to "live with".

Most commercial software users are "price sensitive."  Given
a choice between two products that deliver the "same"
functionallity but one "promises" higher reliability for a
higher price, IMO most will choose the cheaper product.
Given a choice between buying a product with features
available today and the promise that a more reliable
competing product will be available in the future, IMO most
will purchase the product today rather than wait.

IMO, the above statement is inaccurate and ignores to those
entreprenours in the Ada community who have succeeded.  Most
individuals in the Ada community are working full-time on
projects to deliver reliable software to those who demand it.
Most have little or no time for "entrepreneurial" ventures.
Most have financial committments that don't allow the level of
risk associated with developing and marketing a commercial
software product.

While I can't agree with Robert's implication that "one commercial
success" will make all of us rich, I agree with the overall
assessment in his article, above, that the Ada industry today is
in a better position to succeed than before.  I applaud his
efforts to get more individual's thinking about commercial
