The brain is not a "lump of fat". If you desiccate the brain, most of what's left are lipids, yes, but at that point you are not conscious anymore. The brain is a mix of proteins, carbohydrates, water and fat.

A lump of mostly fat then? Seems needlessly specific.

I’M NOT FAT I’M JUST BIG BRAINED!!

Mostly water, in that case

Also fairly sure that electrical impulses alone cannot account for consciousness. If that were "all" there was to it we'd have simulated a human brain by now. There's a few theories about quantum processes being involved but this isn't exactly easily proven.

Didn't it take them a long ass time to do this for a fruit fly brain?

Depends on when you start the timer. The fruit fly brain was only completely mapped recently. There's a simulation of it that runs on a laptop. If that simulation can run on a modern laptop and the map was otherwise available, then it likely could have been done on supercomputers in the decades prior.

I thought they were up to mice now but I might be mistaken.

To simulate a human brain, we would need a complete map of it. We don't have that yet. If the quantum theories around neurons are correct, then the map would be incomplete without it.

I doubt we could simulate it directly without a very specialized ASIC.

The connectome doesn't really seem to be so realistic, at smaller scales sure.
