Actually, I think it's funny how you go right from the Steve Jobs lookalike to a Matrix-y datastream. Is the ride trying to tell us that we're already enslaved by the machines, and it's all Steve Job's fault?
I really don't think that SSE has been "dumbed down". I think the narration is geared toward the current (and future) generations that don't remember what the world was like before the Internet, and this makes those of us who fell in love with EPCOT back in the '80s interpret it as less intelligent.
I hadn't ridden the current version until this October, so I went in with all the criticisms I've read on this and other message boards ringing in my head. I fully expected the descent to be a Journey-Into-Your-Imagination-With-Eric-Idle-style hack job. And . . . it wasn't. At least not in my opinion.
The first time I experienced the descent, I was too busy with the touchscreen to notice the stuff on the walls (or lack of it) until the very end, when the wall acquired sparkly lights right before you exit. When I was at WDW two weeks ago, I paid more careful attention to the descent tunnel. And it's not necessarily worse than previous versions, it's just different. Because people are focusing on their touchscreens, it makes sense that the descent tunnel is decorated with more of a minimalist sensibility. Once you descend though the starfield-grid effect, the tunnel begins to be dotted with those irregularly-shaped triangles, first on the ceiling only, and then eventually they spread to the walls. Halfway to three-quarters of the way down, the triangles are lit. It's all very minimalist, but again most people's attention is going to be focused on the touchscreens.
The real problem, I think, is that there's a contingent of us that thinks Disney took the cheap way when they turned the entire descent into a Jetsony cartoon that you watch on a little screen. Sure, it's generic enough to appear futuristic for years, maybe even decades to come, thus negating the need for a costly refurb every few years when reality overtakes the "future" as depicted in the ride's last few scenes, but when all is said and done it's an uncomplex Adobe Flash game.
Of course, it's entirely possible that all our grumbling about the descent is the equivalent of crochety old people complaining about kids these days and their crazy music, and how in our day we listened to Bing Crosby and liked it. I really don't know.
