.... Top tubes are loaded mainly in tension; downtubes are loaded mainly in compression, and with that information along with the fact that carbon fiber is stronger in tension rather than in compression, one can determine to a good extent which way the fibers need to be laid.

However there equally expensive frames that just look good but are heavy and based in things like tradition. These frames are designed to be around a long time.

A friend who rides a lot has a high end Trek Madone that has 35k miles on he. He just had the drivetrain replaced. This guy has broken frames and cranks on older bikes.

Good with the torsional loads too.
To be a bit more clear the compression issue is not the CF but the shape. Long thin tubes are not good in compression. A block of smartly woven CF would take a load well.
