As a semi-professional prognosticator I'm always tempted by the rhetorical power of statements like The Internet Is Killing X. But, of course, it isn't.
I also try hard to remember:
Something That's Growing Is Not The Same As Something That's Big.
Something That's Declining Is Not The Same As Something That's Small.
If someone offers to give you half of a record company, take it. They may be shrinking, but they're still big.
