Not always. The physical layers are incredibly different, and while it is true that most 1G devices also support 10M/100M, we found the hard way that some 10G switches and NICs don't.
10G no, but all 1000BASE-T NICs require autonegotiation for 10/100/1000 to be compliant.
NICs maybe, but there's a whole heap of cheap home switches and hubs that don't support 10BaseT. I know this from experience.
I've also experienced some quite expensive Juniper DC switches not supporting anything below 1Gbit. Fun times.
Some ISP core stuff too.
