No, I'm not misinformed. I'm quoting Einstein and Hubble.
Susskind is at best pulling your leg. The fact is that String Theory is a giant hoax, anyway. It is *impossible* to unify General Relativity with Quantum Mechanics, thus making String Theory a fool's errand from Day One.
That's why we laughed 20 years ago when String Theory was first proposed, and that's why we're still laughing today; you can't unify QM with GR. One theory must prevail, while the other theory must be trashed.
Choose one.
