Exactly the opposite.
The number of DSP cores used in devices we use everyday has increased a lot.
Look at diagram of any Mobile SoC. Typically there are MANY specialized but programmable DSP cores on those chips. And there are multiple types of those.
There is imaging DSP to do the noise reduction, there is video DSP's for video encoding and decoding, there may be separate audio dsp, there may be some general-purpose DSP also etc.
