Yes, I've heard carbon fibre frames are essentially now regarded as consumable items. Personally, will be surprised if many of the modern ones are in regular use in 20 years time.
Probably about a third of the bikes I've owned have had frame failures (cracked seat tube twice, bottom bracket shell crack, bottom bracket threads rusted out, snapped drop out, rack mount insert pulled out, bottle boss ripped off causing downtube failure, head tube crack). Only one of those preventable by maintenance, and only one caused by a crash. Not a heavy or abusive rider either.
