Boring is good, boring is what people who depend on their machines want. Secrecy and obfuscated roadmaps are the opposite of boring.
An M2 Extreme and a handful of slots is fine, but if it brings with it an utterly unnecessary soldered processor, no ram dimms, no user-upgradable off-the-shelf graphics etc, then we have a problem, because despite what the hype would lead you to believe, all these things that are integrated in the M-series silicon, are slower and less performant than the user-upgradable off the shelf alternative versions, unless you're doing a very, very narrow range of Apple-specific stuff, which is just as fast on a Mac Studio, or laptop.
Take RAM for instance, while there may be a margins of error speedup in integrating RAM, the much lower ram ceiling (especially at first-release prices) means we're much more likely to hit swap, and that is MUCH slower than DIMM ram, so in reality, that integrated RAM will make our computing experience slower.
Same with graphics - it doesn't matter how good Apple Silicon graphics are, they're still slower than dedicated cards, and more expensive for the product step-up price deltas.
There's literally no upside to the Apple Silicon paradigm for a workstation. I don't care how much "power" the AS processor has, the system's integration means it lacks "torque", and torque is what matters to my (computing)truck.
And most importantly, when it comes to calmly being passive and just accepting whatever inevitable fate Apple has decreed for us, pardon my French, but f^&k that. I will rage against this until the cows come home, because Apple Silicon and custom chipsets & hardware is the same paradigm that almost killed the Mac in the 1990s, it's the same paradigm that killed the Amiga, the ST, the NeXT, every unique and interesting computing platform that ever came about. They all died because their weird, unique hardware doomed them to evolutionary backwaters, when they couldn't match the development of the entire rest of the computing industry.
