This is not academic writing. PG Wodehouse and Susan Sontag are not writing academic dissertations. I’m speaking of university dissertations and term papers and the like. Writing graded by academics.
And I am not familiar with the writings of Einstein. But he was known for physics, not grammar. So no matter how many conjunctions he uses and how, he gets a pass from me.
Grammar and usage guide experts might agree it is okay, but your professor might require you to use strict academic style. The golden rule is to follow the style required by the audience you are writing for.
When you are a novelist, poet or writing creatively, you can break the rules all you want as long as you have learned the rules first.
