I generally give you claps. But not this article!

Let's start with some cred - I have a degree in math, I've worked in programming for decades, and In 2014 I was hired by Ripple to write code for their XRP blockchain. Six years after I left, I'm still the sixth largest contributor to that codebase.

First question to you - what does an NFT do that couldn't have been done with strong cryptography and a digital signature in the late 70s, for a tiny fraction of the cost?

The boring old digital signature has a big advantage over the NFT, too - you can attach the signature to the original file, something you can't do with an NFT.

Second question - given that there are over 10,000 cryptocoins in existence, and these days, that anyone could create their own blockchain and coin without even writing a program to do so, can you explain why you perceive cryptocurrencies have "scarcity value"?

NFTs are a scam from top to bottom. Cryptocurrency is a giant Ponzi scheme whose only applications are baseless speculation, and crime.
