It's never described as a dead-end path. It's simply one that has already been trod. Allow me to counter your Nazara with a Legion:SajuukKhar said:As Soverign said in ME1Asita said:Who said anything about chains? The use of Mass Relays only had a negative effect in that it streamlined one potential line of technology, the one that the Reapers had already trod and thus were most familiar with.
the use and dependance of the Mass Effect relay leads civilizations down the path the Reapers cahse for them.
the Mass Effect relays are tools of limiting species technological development by creating a dependency on outside technology and exploiting the races assumptions that since they will always be there there is no reason try try to make more.
The study of the Mass Relays, the citadel, and the Keepers was almost totally banned and attempts to study them were met with imprisonment and death.
It restricts the technological development of races by forcing them down a dead end path the reapers set out.
the Mass Relay system works in this way regardless of if The reapers are physically present or not.
The key concept here is that there's more than one answer to a given tech-issue. By learning about one solution, you focus on that solution and continue to develop around it, especially when that technology is so much further along than what you're accustomed to. That is not inherently a bad thing, nor is it inherently a good thing. And it especially does not mean the path ends abruptly. And regardless of the Relay's continued existence, the vast majority of galactic civilization had already been set down that path and had been applying it on lesser scales for decades at the very least, removing the relays would not put the various cultures on another technological path any more than removing the Citadel's Krogan monument would change the aftermath of the Rachni Wars and Krogan Rebellions.
The study of the Relays was never banned (though opening up uncharted ones was, due to lessons learned from the Rachni Wars), the study of the Keepers was banned because they're essential in keeping the Citadel running and because they literally self-destruct during most attempts to study them. The study of the Citadel similarly wasn't banned, but it was incredibly difficult due to various factors (not the least of which was the fact that the keepers maintained most of its functions and weren't exactly much for explanation)
