Good Lord. I may be Captain Picard, memory-wiped and trapped in the past! With a bit more hair, though.
To paraphrase Dennis Miller: “As soon as virtual reality gets so good that any Joe Sixpack can make love to Claudia Schiffer in his den, it’s gonna make crack look like Sanka.”
I remember reading that they filmed a scene of the Vorgons showing up even earlier, to run just before the final credits, to imply that “sooner or later” (given the vagaries of time travel) they’d succeed, but the scene was cut.
And wasn’t Vash yummy?
I didn’t read it that way… they were attempting to interfere with his destiny, and then admitted that they failed.
And they were going off of centuries-old records… maybe there was something that hadn’t been recorded in history. Picard COULD have faked the destruction of the gizmo after they took it - but he didn’t. 
I missed that earlier. The Vorgons say Picard has fulfilled his role “all too well.”. They’re clearly unhappy he succeeded in destroying the Utat. Picard holds this view of the Vorgons as well, as he comments that they’ll probably use more time travel to try and get the Utat before it was destroyed.
She was a cow.

No, they were still washing out the holodeck from Riker’s bizarre and repugnant desires 
Hell yes. In Forbidden Planet, the Krell all died in a single night after the big machine was switched on and the Monsters from each others’ Id did for them. Our civilisation will die roughly twenty-four hours after holodeck access for all becomes feasible, 'cos absolutely no-one will be minding the store. 
Shaun Ryder of the Happy Mondays said something similar on a BBC celebration night for Star Trek, but he didn’t put it so eloquently.
