Because it's not 10x. If you cool the solar panels (which aren't black body absorbers for longer wavelengths) and GPUs to 80C through a heatpump and have the blackbody radiator at 120C it will approximately work out, 1:1.
Avoid it as much as possible. They'll circle the earth around an axis approximately in line with the earth-sun vector. In practice they might see some eclipse, but only for a small percentage of their orbit.
The inner side of the radiator would be metallized, an anti black body. Together with a bit of vacuum it would thermally be quite far from the PV&GPU. Thermal insulation is easy in space.
You still can't get more surface area than a sphere without crumpling things up. And given the thermal insulation, you can only lose heat via radiation. Radiating heat from a crumpled boundary means radiating it towards another part of the boundary. If there's an "inner side", then it's a sphere (or some other convex shape, all of which have at most the surface area of a sphere).
I don't think you'd want any vacuum at all between the radiator and the heat sources! Thermal insulation is the problem, not the solution. You want the radiator as thermally close to the heat sources as possible, probably via some highly heat conductive metal.
Though the optimal approach might be to ditch the vacuum and use a more terrestrial configuration with circulating air or water or mercury to conduct the heat away. Space is a horrible place to do this in all ways except for... well, space. You do have plenty of room up there. (Well, and power. Lots of solar energy to play with. Which in turn causes its own problems with heat and radiation.)
With a heatpump the PV and GPU would have the evaporators, the radiator would have the condenser. You do this for two reasons, so you can run the radiator hotter (4th power and all) and because the refrigerant is a good heat spreader (better than pure liquid cooling).
With a heatpump, you don't want a thermal bypass, hence the isolation.
Space is not a great place to get rid of heat, but if you need lots of surface area any way for PV that almost solves itself.
You don't put it in a standard orbit, you put it in a polar orbit with near 100% suntime ... obviously.
Obviously you use the backside of the massive area of PV you need, for an equally massive area for HOPG radiator films with condensor coils (because obviously you use heatpumps for cooling, not pure liquid).
Consider the obvious ways you'd actually do it, not the most naive ways.
The GPU pods obviously won't weigh the same as a terrestrial rack. Space based solar arrays obviously don't weigh the same as your hail and storm resistant panels on your roof (see ROSA, but there might be another 10x weight reduction if using flexible solar in tension from rotation). Noone cares about a couple 100 ms extra for first token.
Solar wind and drag are in my opinion the biggest issue. Problem : it's a giant surface catching drag and solar wind. Solution : it's a giant solar sail. Controlling the angle of PV for useful thrust, that's never really been done for a satellite.
It's not meant as a workstation/tinkering system, the card without networking is not the main aim. If you're willing to pay 4k for 96GB, just get 3 with networking.
That said, it missed the boat on MoE. The future is two tiered memory systems, NVIDIA has already announced they are doing that. Ideally these cards should have 4-8 DIMM slots for a couple channels of DDR5.
That would also make them far more useful for workstations/tinkering.
Is Rasmussen really in favour of a GoF ban and destroying the academic value of the background of the majority of her professional friends in the field? Cause I can't really find her calling for a ban, quite the opposite really.
This is the problem with virology, it IS GoF. Expecting virologists to be objective in this is expecting the impossible, like expecting the WHO to apologize for sending Daszak as head of the fact finding mission. They were either THAT incompetent or THAT self interested in maintaing GoF/virology, damn the truth.
I suspect virologists still see themselves as guards on the wall and that we can't handle the truth. Which we already know from the early emails is how they thought early on, why should I assume their propensity for dishonesty has changed?
Kick off all ISPs which refuse to do good ingress/egress filtering. Kick off all customers which absolutely positively need to be completely exempt from the filtering because of their ultra special snowflake networks, when creating source spoofed abuse a couple times. So now you have an internet with reliable source IPs. Allow ISPs for their customers to push firewall rules blocking abusive traffic to the originating ISP, subject to some fair use rules. If an ISP's firewall slows down because they are overloaded with rules for obvious abuse from their customers ... well that's working as intended then.
There's only so much developer time and management focus. "This will help us cement our monopoly on software distribution without being too obvious to regulators" is a good pitch.
PS. I'm sure the people who pitched it and their managers are all sufficiently skilled at lying and lying to themselves to not put it or even think in those terms.
You can ship macOS native games on Steam as well. People need to stop throwing conspiracy theories. Their main motivation is to make sure games are native to macOS so they can take advantage of system-native features, which Win32-translated games won't. Otherwise games running on Macs will always be kind of janky and run slower than Windows.
So now they are propping up an ecosystem on which open computing will always be a second rank citizen at best. I wonder if they are all happy about it in retrospect, wine got patches, DXVK gets to be a brick in the wall of Apple's garden (if Valve can't distribute it, it's useless to them in the grand scheme of things, normal people want a one click install).
Monetarily good for the devs who ended up on Apple payroll, another nail in the coffin for competition and open computing at the same time.
