(fusion is -always- just a decade away, perpetually, lol)
Wasn't it perpetually 20 to 50 years away? I'm not an expert on the space. But new computational methods and magnets seem to be genuine steps forward.
Fusion Reactor First Wall Cooling

One of the designs uses 3D printed silicon carbide vacuum vessel cooled by a layer of molten lead and a layer of FLiBe (a molten salt made from a mixture of lithium fluoride (LiF) and beryllium fluoride (BeF2)).
https://en.wikipedia.org/wiki/FLiBe
The lithium component of FLiBe is used for breeding of the radioactive isotope tritium, which will be extracted from the salt and used for making the deuterium-tritium fuel of the tokamak.
On a serious note: I wonder how practical and safe it would be to build fusion pants close to city centers in order to harvest the excess heat for district heating. Would be a boon in e.g. NYC which already has a large district steam system. You can do cooling too, look up "steam absorption chiller."
The cost/benefit for doing this seems pretty similar between fusion as gas power. We don't usually do this with gas, so I guess it's probably not viable for fusion.
If I enable advanced mode, the "exiting" in Heating Power (exiting) gets overlapped with corresponding numbers
