YES.  Computers think bouncing is OK, the conservatism is fixed, half use
Haldanean bullshit algorithms, they don't support correct profiles, most
recommend ascent rates that are too fast, etc., etc. All the same reasons
they aren't OK for bigger dives, as recently discussed, still apply.

But, In addition to all their technical shortcomings, the biggest problem I
have with computers is that reliance on computers promotes a diving
population with no knowledge of decompression theory and how it applies to
what they're doing.  So, instead of knowledge, we have reliance on gadgetry,
and most of the diving population appears to gravitate towards replacing
knowledge and technique with gadgets and shortcuts. This is the mentality
that gets people bent and killed.

There was a time when I was less Draconian in my acceptance of some rec
diving practices, but my tolerance for idiocy among any aspect of the diving
population has been steadily declining since my first body recovery.
