I doubt you'll find anyone who seriously argues Einstein's point in this day and age. Even when Einstein was alive, there were only two other physicists who seriously challenged the quantum mechanics theory, and they quickly dissolved into the ether, leaving Einstein's writings as the only real dissent from quantum mechanics.
At this point, quantum mechanics is considered to be gospel, which is ironic. And it's especially perplexing when one considers that it is inconsisent with relativity, which is also considered to be gospel. And even more perplexing when you consider that quantum mechanics has no explanation for the existence of gravity, yet clearly gravity exists.

All true,
but in the realm of electromagnetism quantum mechanics is thoroughly sound. It has predicted (later confirmed) most of all we know about electron bonds (thus, chemistry and solid state physics). It has given us all of modern digital electronics.
