Naturally. I'm not disparaging that there might be limitations and/or exceptions. I was highlighting that as general practice, we've gotten pretty ok at pressing bearings.
I'm not a materials scientist, but I don't think the loads exerted on bearings used for high performance parts will compare to a human powered bicycle. I can grasp the limitations and in a sense, the flexibility of the material in comparison to say...an alloy shell, but I'm being quite general.
Most of the complaints regarding press fit creaking I've actually experienced were on aluminium frames rather than carbon, which surprises me as I'd have thought we have got pretty good at machining or casting to high tolerances.

Trying to do the machining on the cheap...that's the problem.

I don't think it's the flexibility of the carbon BB shell that's an issue, more the difficulties in getting tight press-fit tolerances in something that's moulded rather than machined. For ali frames which can have the BB shell machined after welding there's no excuses.

Not into carbon fibre bearing housings though. That's one thing that people who use composites a lot like F1 teams and aeronautical engineers try very, very hard to avoid. If you look at an F1 gearbox with a composite housing, all of the bearing carriers will either be bolted on or will be alloy shells co-moulded into the housing. You can't get sufficiently tight tolerances with carbon alone.
