[X-men days of future past]What happened?

Spoiler warnings ahead as always.

Logan's mind was sent back in time, the assassination of Nixon and his gang of suits was foiled, Mystique/Raven saved the president. Yay for the heroine.

And Logan eventually wakes up again captured by Trask, but his mind zips back along the timeline to the future where he's a history professor (What really?) working for Charles Xavier.

What happened to the rest of the world? What was the ultimate impact of the sentinel event?

Additionally, where the hell did those robots come from in the 70's?
As far as I know the dawn of the microprocessor was still almost a decade off. How did Trask manage to build autonomous humanoid robots before then? (I mean Dinklage is awesome. But I'm not allowed to break the 4th wall here.)

He was lifted from the river by Mystique posing as Stryker, not Trask.

>What was the ultimate impact of the sentinel event?

Because Mystique didn't kill Trask (and Nixon et al.) the sentiment toward mutants changed from hostile to friendly (or neutral at best) so that the "dark" future never happens.
