Value can be transferred between programs through Ethereum. The tokens you mentioned have value, because people are willing to exchange them for money. So it's not an inaccurate statement. Web3 provides the standardised API through which these programs can communicate.
> Whether they have value is irrelevant as far as the technology itself is concerned.
I'd argue that it's not irrelevant. The whole point of the technology is, at risk of more 'marketing buzzwords', a decentralised way of moving value around (moving digitised tokens which have value on the market, around).
I had a look at your post/comment history. It's almost exclusively cryptocurrency focussed. I'm curious why you spend so much time discussing a technology you clearly don't think has a future.
Why are my comments focused on cryptocurrency? Because I like to discuss cryptocurrencies. I have thought a lot about them, and I think it's an interesting phenomenon from an sociological point of view. Plus, I like arguing with people who I think are wrong.
What does that even mean? How is a global API going to support the enforcement of a rental agreement? Or of a bond indenture? Who is actually going to enforce the contract? And what is the role of a global API in that? And what do you mean value transfer between applications? You want to transfer "value" (like a bag of rice?) between computer programs??? None of that makes the slightest sense. Meaningless gibberish intended to fool gullible idiots into thinking that blockchains are some kind of disruptive technology that is going to turn everything upside down. Nonsense. It's a pump & dump scheme, and little else.
