First, it is very easy to prove if you are Satoshi:

Take the key from genesis block or from transaction paying to Hal Finney. Sign a message that includes your meatspace name, your relation to Bitcoin and the recent timestamp in a form of a recent block hash (that’s how you prove that the message could not be fabricated long time ago and/or with careful choice of contents). Publish the message and the signature anywhere.

No one has done that yet.

Second, it’s quite easy to prove that all claims by Mr. Wright regarding his link to Satoshi are either irrelevant (such as general knowledge of how Bitcoin works) or outright fabricated (such as backdated PGP key demonstrated last year, or a signature copy-pasted from a Satoshi’s transaction).

Third, it’s easy to see how mass media and some prominent voices in the Bitcoin space are turning “burden of proof” upside down. Some express doubts, but still prefer to trust (!) and believe (!!) even after being educated about the invalidity of the presented “evidence”. They still wait for a “better proof” coming from Mr. Wright.

In this story Mr. Wright brilliantly demonstrated who should not be trusted anymore on any matters in finance, cryptography or Bitcoin. Oh, what the heck, who is not to be trusted, period.
