What ever happened to Classical Unified Field Theory?

TL;DR Summary

What happened to unified field theory?

Are there currently professional physicists who work on Einstein’s quest to unify the gravitational field and the electromagnetic field (as classical fields), or has this idea been completely abandoned? Is it simply a hopeless endeavour?

If you're referring to Einstein's "nonsymmetric UFT", well,... imho it's total rubbish. His cavalier manipulations of the two lower indices on the connection components shows that he didn't really understand the true purpose of the connection object in the context of differential geometry. It's "indexology" (where I invent that term in analogy to "numerology").
