Defending Craig Wright's eccentricities is always going to open a huge can of worms that I won't likely have time to close with the standards of argumentation I'd prefer to uphold here, but in the interest of maintaining at least a degree of accuracy I feel obligated to mention some things that will be apparent to all who have undertaken a deeper investigation of his work.
If the claim is that Wright merely repackages older material, off the top of my head:
- He brought up Turing completeness in Bitcoin for the first time in late 2015, when no one else was talking about it.
- I never saw anyone else talk about network graph theory before him, not even a trickle, whereas he is a waterfall on that topic. It has turned out to be an elephant in the room and a major key to the whole scaling issue. Were that his only contribution, I would class him with the best in the space on that alone.
- Besides Satoshi indirectly, I saw exactly two people saying anything along the lines of nodes completely useless for regular users to run before CSW did: Jorge Stolfi directly (calling non-mining nodes "abominations") and @Tomas van der Wansem indirectly. Both of those are pretty obscure, just being a few reddit comments. CSW gave even more straightforward reasons that make eminent sense in hindsight, as well as copious examples from early code and Satoshi writings that had been hidden by some semantic flourishes in the meantime (the meaning of "node" had subtly changed through Core's reign, with the result that Satoshi's real views remained hidden in plain sight). He thoroughly harped on the semantic issues.
- His criticisms of various altcoins are often quite novel: IOTA (graph theoretic issues), ETH (novel critiques of PoS and short block times), BTC (novel critiques of Segwit, to my knowledge fleshed out much more than anyone who may have hinted toward similar issues), LN (pointed out routing as others did, but noted specifically the multiple-depot travelling salesman problem).
- Stag hunt dynamics of mining.
There are so many more of these that it is pointless to go on. No matter one's position on CSW, it would be hard after thorough investigation to claim his problem is a lack of original material.
The argument will shift to, "But he is wrong about this and that," or, "He didn't specify this or that enough to warrant such sensational mention of it." Wrong - possibly, but I haven't seen any major examples yet (and were there any, that wouldn't make much difference to me as I haven't found anyone who gets nothing wrong). Underspecified and coy - yes, frequently. It's frustrating to some, but tantalizing to others. Personally, given his major contributions to my understanding heretofore, I'd rather see such hints than nothing at all.
I also haven't seen much blind parroting of his ideas. I've mainly seen people repeat the ideas that do make sense. For example, I don't see a bunch of people going around saying selfish mining is wrong, even though he spent a lot of time on that. I don't see people talking about Turing completeness unless they have some expertise, and those that do generally talk about it from a different angle. The node ideas have been a hard sell; I've been down in the trenches pushing them for months because they make a lot of sense to me (and it is striking how clearly Satoshi never said anything to suggest Core's idea of "full nodes," which had somehow been inured to a fixture of Bitcoin even among anti-Core folks).
He does of course repeat some ideas himself, as we all do, and as is expected for someone as thoroughly read as he is (note that the issue of his degrees should now no longer be in dispute, but as with everything else, he doesn't lay it out on a silver platter for investigators).
Lopsided genius is going to be more and more common going forward as we enter an age of unprecedented specialization and unprecedented levels of autism. No longer will brilliance always present itself in the more complete package of a Mises, a Hume, or a Hayek. Especially not if the person is just a guy who had a twisted love-hate relationship with being in the public eye in the first place. But this is getting into the proper way of evaluating evidence of claims of this nature. A post for another time, if I ever have a week or so free to try to cover such a complex topic as this enigmatic man.
