Do we err in making the assumption that all carbines were primarily horse-oriented weapons? Seems that the trend to the shorter rifles ( M1903, Garand, Mauser 98, Mosin-Nagant, etc.) suited mounted troops very well, and the "second generation" of short weapons was primarily required for vehicles with their cramped/awkward interiors.
There is almost sort of a generational shift in some instances. The short rifles wiped out the carbine in most, but not all armies. Some armies that retained carbines made pretty wide use of them, or non cavalry use. The late war Soviet carbines weren't really mounted arms, and the VZ33, when adopted by the Germans, wasn't adopted for mounted use. Of course the M1 Carbine in no way contemplated mounted use.
I suppose the M1 might have arguably ushered in the modern era, for good or ill, in regards to carbines. Darned near all the most recent assault rifles are really carbines.
