Comparing normal living beings brains with Orion's Arm scale:
[https://orionsarm.com/eg-article/4a53a8f690f09] Nearbaseline human ("Neb") has 1.5 kg brain mass, 1500 cm3 brain volume, 1e18 (1000000000000000000) ops/sec speed and 1e18 bits storage.
[https://en.wikipedia.org/wiki/List_of_animals_by_number_of_neurons] Modern human has 8.6*10e10 (860000000000) neurons in whole body, ~1.5*10e14 synapses in whole body, and 16340000000 to 21000000000 neurons in cortex. It weights 1200-1400 grams. 15000000 to 17500000 neurons per gram.
For comparison, ravens are comparable to primates, having 2.171*10e9 neurons in entire body and 1204000000 neurons in brain. That's despite their brain being tiny, 5-10 gram weight. 60200000 to 150500000 neurons per gram, about 3.44 to 4 to 8.6 to 10.0(3) times more neurons per gram depending on how you count it.
There are more ops than there are neurons. As such, if dropping fractions, 1 neuron in whole body gives 1162791 ops and bits. 1 synapse gives 667 ops and bits. Each neuron in cortex gives 47619047 to 61199510 ops and bits.
So, how smart a human could get if lots of neurons were grafted onto his brain. Neurons don't even have to be from same species, due to hematoencephalic barrier [https://www.nature.com/articles/d41586-024-01222-1] [https://www.statnews.com/2022/10/12...nt-brain-lead-rat-to-water-and-make-it-drink/] [https://med.stanford.edu/news/all-news/2022/10/human-rat-brain-neuron.html]. And to make sure it all fits, cranioplasty can be re-purposed to make extensions to skull, to make it bigger. And metal collar-like device can transfer head's weight onto the shoulders, so head doesn't fall off. This is Cortex neurons - as brain is embiggened, not whole nervous system. The actual Singularity starts once grafted neurons vastly out-number the original neurons.

Well, turns out that SL:1 is out of our league for now, unless you make building-sized amalgamation of brains. Superbright/Superturinggrade is within reach of our current technologies. To keep in mind, Superbright/Superturinggrade represents Extraordinary Genius, "normal" super-scientist we see in media [https://vsbattles.fandom.com/wiki/Category:Super_Scientists]; SL:1 and beyond is lovecraftian overmind, outright incomprehensible to normal humans, like humans are incomprehensible to microbes. Singularity could be kick-started this way, if super-scientist invents better brains; but even without Singularity, this would be very useful.

Mobile variant:
- A normal human would have 16340000000 to 21000000000 neurons - which means 1E+18 OPS for Average Human and1,28519E+18 OPS for smart human. Normal Human is Nearbaseliner, but Smart Human is actually equivalent to low-end Superturinggrade. 100% to 129% of average human brainpower.
- A human with entire raven's brain grafted in would have 17544000000 to 22204000000 neurons - which means 1,07368E+18 OPS for Average Human and 1,35887E+18 OPS for smart human. This didn't do much in terms of breakpoints. 107% to 136% of average human brainpower.
- A human with entire another human's brain grafted in would have 32680000000 to 42000000000 neurons - which means 2E+18 OPS for Average Human and 2,57038E+18 for Smart Human. Still in Superturinggrade range. Extra encumbrance is no larger than that of modern helmet; but if helmet is worn on, there will be problems with neck. 200% to 257% of average human brainpower.
- What if we take more efficient brains? 120 to 280 whole raven brains grafted on. Thus giving from 1,4448E+11 to 3,3712E+11 extra neurons. That's plus human's own brain, with 16340000000 to 21000000000 neurons. Thus from 1,6082E+11 to 3,5812E+11 neurons total, and 9,84211E+18 to 2,19168E+19 OPS total. Still superturinggrade. 984% to 2192% average human brainpower.
- What if human had brain 2 times larger than upper level of norm, and it was as effective as raven's brain? It would be equal to 280 to 560 raven brains, for total of 3,3712E+11 to 6,7424E+11 neurons, for 2,06316E+19 to 4,12632E+19 OPS total. Still superturringrade. 2063% to 4126% average human brainpower.
Immobile variant:
- So how much neurons we need for Sl:1? Upper border of Superturinggrade is 1e20 OPS, or 10000% (100x) human brainpower; minimum SL:1 is 100000% (1000x) human brainpower; and average SL:1 is 1560000% (15600x) human brainpower. Thus 1634000000000 to 2100000000000 neurons for High Superturinggrade, 16340000000000 to 21000000000000 for Basic SL:1 and 254904000000000 to 327600000000000 neurons for average SL:1.
- And how many brains that means? 100 to 129 human brains for High Superturinggrade, 1000 to 1285 for Basic SL:1, and 15600 to 20049 for average SL:1. Weight is 1200-1927.5 KG, 1200-1542 KG, and 18720-24058.8 KG respectively. Now think about monstrously large life support system of this thing - life support must be larger than brain itself; we can't even build such life support systems yet.
- And if we use raven brains? 1357 to 1744 raven brains for High Superturinggrade, 13572 to 17442 for basic SL:1 and 211714 to 272093 for average SL:1. Weight is 6.785-8.72 KG, 67.86-87.21 KG, and 1058.57-1360.465 KG respectively; that's low end, high end is double that. A lot more compact, but it would blow up the budget since there just aren't that many ravens on market. Our best options would be just using all brains at hand - from farm animals (e.g. pigs, cattle), captured vermin (e.g. rats), volunteer humans, etc - everything which has neurons. And also, peripheral nervous system can also be dismantled for neurons for grafting.
Well, turns out that SL:1 is out of our league for now, unless you make building-sized amalgamation of brains. Superbright/Superturinggrade is within reach of our current technologies. To keep in mind, Superbright/Superturinggrade represents Extraordinary Genius, "normal" super-scientist we see in media [https://vsbattles.fandom.com/wiki/Category:Super_Scientists]; SL:1 and beyond is lovecraftian overmind, outright incomprehensible to normal humans, like humans are incomprehensible to microbes. Singularity could be kick-started this way, if super-scientist invents better brains; but even without Singularity, this would be very useful.
