Please provide examples of these truely talented artists that will be remembered. I want to listen 
I was thinking of the pioneers of the last 50 years, from the introduction of the electric guitar, the multitrack recording studio, the analogue synth, the sampler and the DAW... All these things have been used and abused... But now we only remember the artists who were good... Not necessarily who were the most popular
The first artist that comes into my head are the Chemical Brothers and maybe Lady Gaga
not overly impressed by Lady Gaga, she doesn't write or compose the music (she has "input" to get a credit, but that is often little more than sitting with the production team during a session), but her production team have found a formula that does work and they use it well.
Overrated would be the Prodigy - they are shit.
I'm no fan of the Prodigy, but Liam Howlett's smapler work on Fat of the Land is exceptional. I would have to say that Fat of the Land was really pushing the boundaries for samplers at the time, it's easy to do all that stuff now... But to do it on a few Roland W-30s and akai samplers in the late 90s was amazing. I would say that if you listen to that album from a technical stand point you will appreciate it more
