Why the ending did not work (repost)

The Catalyst sees things as an inevitability not because it never evolved or ignores what Shepard has done. But because the society they created and the way it was developed was following down the same path others have followed. The same path that caused the extinction of races that led to the Catalyst being created in the first place.  When you are on the path you can not see it's ultimate end point. The Catalyst how ever sits above it watching and analyzing and can see the end point that the current cycle is walking.

On that path the Quarians created VI's that evolved into their own form of life. Their reaction was one based on fear in which they attempted to shut down and wipe out the newly awaken Geth. Which resulted in a war that left the Quarian race on the verge of extinction. In responds the rest of the galaxy at order of the Council rounded up all AI's peaceful or not and had them executed. The Krogan got less despite casing 4x the amount of death and damage.

The Reapers are invading. Every race is fighting tooth and nail to only be slowly pushed back and yet the Quarians launch an all out attack on the Geth simply because they can. If they were willing to do that when the Reapers are invading then they would be willing to do that in peace time.

All of this adds up. Were another race in say Traverse create a race of Synthetic beings and they found out about the history of how they have been treated by the rest of the galaxy it would be more then enough reason to go to war and wipe out organics. Because they wouldn't be safe until organics were wiped out.

Any unity gained from the war was only gained because of the war. The Quarians would have happily blown the Geth into oblivion. The Turians and Krogan would have stayed blood enemies and would have no reason to cure the genophage. The Batarians would still happily be engaging in slave raids and rendering people broken shells of their former self due to their treatment. Nothing would have changed and they would have continued to walk down that path. Salarians would still be meddling in the affairs of lesser species fucking them up much like Krogan.

This is all basic cause and effect happening.

The entire reason the Catalyst and by extension the Reapers exist is because society is set up in a way that causes inevitable conflict between organic and synthetic life. Which due to the advantages synthetic life has committed genocide on the race that created them.  And there are more then enough echos of that in the game world.

And that is the thing only Control and Synthesis at least attempts to address the issue. Destroy removes the Reapers and certainly increased the unity among organic races that wouldn't have existed before. But doesn't really change the landscape of society in regards to synthetic life. And as technology advances set ups like the Geth become more and more possible. Though with much higher intelligence obviously. Eventually there would need to be a technological stagnation or deal with a series of conflicts resulting in the loss of millions if not more lives. Which only enforces the negative view of them. Which in turn enforces the view of newly awakened synthetic life that they can't trust organic and their very existence is in danger as long as organic life exists.

Yeah. Like what happened to the Citadel war assets that Shepard gathered? Too bad ems wasn't effected by that. Shepard looks at the ems, after completing Cronos, and  sees that its been reduced by however much.

Who knows. Maybe TIM got in the drivers seat, started the engine, put it in gear and put his foot on the accelerator. The reapers escorted him to Earth.

The biggest thing is there was no SOS sent. If so, did the reapers block it? I'm sure Bioware would give a similar answer the catalyst gave about the crucible. You don't need to know, and there's not enough time to explain.

The issue with there being no long-range SOS first appears with the Cerberus Coup.  The Normandy (and every other ship around the area) was completely unaware of an issue until they were attempting to dock... and then only got word of what was happening from Thane.
