You're whining and saying "
Sony is doing a piss-poor job with the PS5 this generation". Their software sales prove you're wrong.
Sony isn't doing what you somehow idealized Sony should do, but your needs and wants isolated are irrelevant for Sony's financial performance and duties to its shareholders.
Just so you know, crying harder won't help.
And even if we do accept the goalpost change to "poor job at pushing their own hardware", it's still born out of ignorance.
All 7 consoles from the 8th and 9th generations have used AMD x86-64 CPUs and AMD GFX7-GFX10 GPUs. GFX10 is 100% compliant with GFX7, so it's a superset of the former.
On Sony's side, the main purpose for this is for
time-to-triangle to be progressively shorter and tackle the ballooning cost and time to make games.
Mark Cerny puts a lot of emphasis on this subject in his presentations.
For 2 generations straight, there's been no crazy architectures for consoles anymore. There's no 16 pixel pipelines for texture effects like no other console can do but 10 guys must code for 3 months for it to work like the PS2. There's no 7 core vector processing unit that can assist its lackluster GPU in running pixel and vertex shaders like the PS3.
There were consoles with an 8-core Jaguar CPU that performed just a bit above an 8-core Jaguar did on a windows PC, GPUs that performed just a bit above GCN discrete PC GPUs. Now there are consoles that perform similar to a 8-core Zen2 and a RX6700 / XT. Lack of Windows overhead and some low-level optimizations help, but not in a very substantial way and the tendency with everyone having 8+ core CPUs is for this overhead to become irrelevant.
So whatever you're waiting for, some secret sauce that makes all games look and run like they could be running on a RTX5090, isn't coming.
That's why the PS4 had some of its best looking games releasing in its launch window like Killzone Shadowfall, and on the PS5 it won't get that much better than e.g. Demon's Souls Remake.
Sony didn't do a poor job at pushing its hardware this gen. They did the best job at pushing its hardware this gen and the one before, by providing devs with access to eloquent enough SDK + documentation that let them push the hardware right on the first year. Same for Microsoft.
