What, exactly, about Reaper hardware is distinctive enough that the Crucible would target only it? It can't be the Reapers' cyberorganic nature, as EDI isn't that. How does that make more sense than targeting software? Also, you failed in that post to explain why it's impossible for it to target AIs. Indeed, "AI" doesn't even appear on that page. You also appear to be inventing something that didn't exist in the game (exposition from EDI) and failing to comprehend that "why are you here?" is a question that could apply to Shepard making it into the inner Citadel at all, not just to the Catalyst's platform. We also, well, see that the Catalyst wakes Shepard up by speaking to her.
I did not fail. I made an airtight case for why it's absurd for it to be able to target Geth without indiscriminately destroying all technology.
We already know Reaper hardware is distinctive because EDI can detect "reaper signatures", per ME2. EDI's blue box (i.e. her brain) is made from Sovereign's . Patrick Weekes said so himself (and, yes, the game does too) and stated that was the reason the writers decided she would have to die with them. As Reapers are synthesized (i.e. organic/synthetic hybrids) for the crucible's blast to be designed to break down that particular type of tech isn't too farfetched. It's a particular technology.
In the case of Geth there is nothing physically that identifies a Geth. Geth can be any tech. A starship, a helicopter, a Qurian suit, a space station, a server, a data pad, etc. The Protheans, who designed the Crucible, would not have known what a Geth is much less designed a blast to target even the standard Geth platform (which would not be enough to destroy all the Geth even if it could because they're uploaded into other non-geth designed objects too). The current cycle's races didn't even know exactly what it would do. Only that it would destroy Reapers per the Protheans' claim. So don't think for a second that they had the knowledge to tweak it to kill Geth.
A husk is not a AI. Note that the husks are completely vaporized. If it targets AI (which they aren't, but for the sake of argument let's say they are) why would it vaporize the bodies? Why don't the Reaper ships vaporize? Because only the terminator inside is synthesized like the husks. If it destroys anything synthetic why don't all the citadel fleet ships disintegrate? Kasumi's grey box? Shepard's synthetics? Data pads, Qurian suits, etc., etc., etc. The Kid claims synthetics, which it explains to be "technology you rely on", will be targeted. He either A.) lied or B.) overestimated the Crucible. In either case the affect of being "targeted" and "affected" amounted to nothing tangible. This is an objective fact that is shown in the ending. It doesn't do anything noticeable to non-synthesized materials in high EMS. In low EMS it destroys everything indiscriminately.
Shepard simply wakes up and is on all fours. When he looks up the kid is approaching. The Kid does not wake him up in that scenario.
