I give you Daft Punk with Nile Rodgers as a counter example.
On the other other hand… guitars still make some of the best 'pluck' sounds. And I say that as someone who owns a x0xb0x, a JP-8000 and an Alpha Juno. People spend a lot of money on synthesizers that can get even close to the immediacy of an electric string. And modern samplers are so accessible you can take that electric string and do whatever you like with it.
