PS4's CPU is trash, it's barely an improvement over the 8 years olde Cell CPU. Maybe that plays a role.

What? It's a massive improvement over Cell.
Then again, Jaguar is still horrible, but it's still much better than Cell ever was, but that's to be expected, consoles haven't taken CPU performance seriously for a very very long time.
The reason for the lack of backwards compatability though is one of hardware, the Playstation 2 is radically different than the Playstation 4 in many aspects that makes a hardware based solution simply unfeasible.
Sony tried the hardware approach with the early Playstation 3's, the extra processors required drove up costs, it would have been possible if the Playstation 4 was an architectural evolution of the Playstation 2, instead the Playstation 4 is more like a cousin of a Mid-range PC.
However, the Playstation 4 is plenty powerfull enough to offer a fully software based approach and would even be able to employ techniques to improve image quality. (I.E. Upscale to 4k, then downsample to 1080P is one option, then apply some Anti-Aliasing and texture filtering and some post-processing effects.)
The reason why it would work is one of low level hardware understanding by Sony, emulators on the PC work by making the PC "Act" like it's a Playstation 2, some calls/commands require multiple passes to perform the same function that would be done in a single pass on a console, hence why on a PC you need a massively more powerfull system to pull it off.
However, Sony is a for-profit company, they are going to be more inclined to offer a paid approach via the cloud and lock you into the platform than a free one, it's not going to be ideal, but those are the cards that were dealt.

"To put it in lamens term think of Jaguar as a car that does 100 kilometers per hour, constantly, regardless of the road conditions.
Think of the Cell as a Car that does 50 kilometers per hour constantly, however when the road is straight and there are no bumps in the road it can accellerate to 150 kilometers an hour.
Thus, over time because the Cell has such a varying top speed, Jaguar manages to get to the finish line first."
These are your own words. You said that in a perfect world Cell could theoretically outperform Jaguar at some tasks. Yes you still said Jaguar averages better but who expects otherwise from a much more recent technology? It's not a real "generation" improvement.
Crytek's president himself said PS4 CPU's isn't much of an improvement over not only Cell but also X360's Xenon.
With that been said, you're making a very good point about the cloud and gaikai. It could even explain why they ditched CD compatibility as well so you buy PS1 games through the cloud.

I do remember posting that.
However, that's not exactly what I would call an accurate depiction of performance and it should not really be construed as such, I was trying to convey the relative strengths and weaknesses of each CPU architecture.
I also personally have zero idea what the newer instructions found in Jaguar are going to do for gaming performance either, especially AVX, however Jaguar is still a massive improvement over Cell in many aspects, such as Integers and Double Precision Floating point, something to keep in mind is that game engines and games aren't always static in the types of math they use.
I do agree that it's not a generational leap however, but that doesn't mean Jaguar isn't a massive improvement overall and it still pales in comparison to any decent PC CPU, but that's to be expected with such GPU centric designs which will offload some of the processing typically done on the CPU anyway.
