If I remember correctly, Einstein discarded the cosmological constant (or at least disavowed it) because it was simply a number he made up to fix
calculations that didn't work out. It was a fudge factor with no meaning, meant to fill a gap in understanding.
During this video, I don't think there was any mention of a meaning for this constant... just the statement that it was important for some reason.
Without that reason, I don't think we can say Einstein made a mistake here. What he was saying is that there is something wrong with this -- and it
can be patched with this number. This isn't the solution, but I've gotten it as close as I can.
Until it has a meaning, it's not a solution... just a number that magically makes things work. Much like Dark Energy and Dark Matter. These are
things that make the numbers work, but which we haven't and cannot observe right now. We'll get back to you on that.
Most likely, Dark Matter and Dark Energy are vast groups of forces and particles and interactions we have not yet even conceived of or measured, and
not any one distinct thing.
I agree that the cosmological constant is interesting, but largely because we can't tell what it means yet. Maybe it's a number meant to represent
"...and all that other stuff"
