The RSX in the PS3 was adapted out of a 80W TDP NVidia 7800GT, the PS GPU in the PS4 out of a 150W TDP Radeon HD 7850. 150W is pretty much the maximum a console could take in total, hence why such a big jump was possible between the PS3 and the PS4. But since we reached the limit here in such a small case as a console has, it cannot grow as fast anymore. Compounding to this issue is also the fact that production nodes shrink at a much slower pace since the 32/28nm process, which in the past made such jumps much easier as smaller processes mean less energy needed and thus less heat.
While your way of thinking seems sound to someone less tech versed, it can't stand against a deeper analysis. Like I said before, it's feasible, but not without a bigger case than the XBO has and a pretty hefty pricetag attached to it.

I'm talking both about the pattern and what has been happening currently just as well.
As I said, the PS4 Pro more than doubled the PS4 flops in a 3 years time frame, so I don't see why the PS5 can't double and add a bit more to the Scorpio flops, three years after it.
I'm not trying to do any analisys, I just don't see why it can't happen, and power usage is a non factor up until now, the PS4 had a good airflow design and a bigger version like the Pro could keep the heat by adding just a single extra layer while more than doubling the power. If at some point it starts becoming just too much, making a better cooling system could just fix it, instead of just throwing a huge case, like we just saw the Pro do as well.
I'm by no means saying you are wrong, as you just pointed I'm not really a tech versed guy, I'm just not, really, but the patterns are pretty solid and the newest examples still keep backing them up very well, so I'm keeping on it.

Let's extrapolate:
it took 7 years to reach 8x the power of the PS3
it took 3 years to (a bit more than) double the power of the PS4
This would mean 6 years to quadrouple and 9 years to reach 8x the power of the PS4. In short, that would even mean 2022 instead of 2021 like I said in my first post.
@bolded part: It has been since the release of the Xbox 360. Red Ring of Death, anyone? The PS4 is also pretty close to it's limit, and the Pro even more so.
@italic: and a die shrink to 14nm, and a change to GCN 1.3, which both did actually much to reduce the power needed. Otherwise that one little extra layer wouldn't have done much to keep the chip from throttling due to overheating.
@underlined: A better cooling system would need a bigger case to fit in, especially as it would need bigger ventilators to get all that hot air out of the case and fresh air sucked into it. The cooling system of the PS4 pro is very performant - but it couldn't get increased without also increasing the size of the console. There's a reason why even the smallest (high end) gaming PCs are so big compared to consoles.
