I somewhat agree with you.
Einstein copied from/built off of many others, prompting some physicists to give the credit for relativity to Lorentz and others? Yes
Einstein was weak enough, mathematically, that he needed Hilbert (and even some interns) to help him with the math? Yes
Einstein did little after SR/GR? Yes
Even worse, in my books, is that SR discarding the ether was the single most damaging thing to happen in physics in the last 110 years.
GR saying the ether can be there, but is not needed, did not fully reverse the gaff of SR.
Einstein then vacillated about the ether for the rest of his life, coming out both for and against numerous versions of the ether, before finally settling on a name-changed ether.
Bottom line? Einstein played both sides of the ether fence, and played games with words, rather than advancing physics and further than SR/GR.
On a non-physics level, I like Einstein. He was a thinker, philosophical and a pacifist. And he didn't wear socks...something I haven't been able to give up.
