👍 I totally agree with you.

"blockchain" is a wonderful technology, but that doesn't mean you are allowed to be stupid and make stupid investments

There are a lot of lemmings out there, willing to follow which ever guru has the fanciest promises. Usually if something seems to good to be true, it contains false hopes.

link your fridge to this global network called "the web" and deliver groceries to your door, without you moving a finger. It was the fridge which was responsible for reading the barcodes of the products you took away or squeezed in it. A small computing device would have been keeping track of all these movements, calculate the remaining supply and order whatever you need to order in such a way that you will never have an empty fridge any more. 20 years after, we have no successful Webvan. Not even a proof of concept that I am aware of.

Roughly 18 years ago, in San Jose Costa Rica, there was a very short test run of smart fridges. The make of the fridge was LG, I believe and when you bought one of these hugely expensive fridges and connected it to the internet, you could get you groceries delivered form one particular store called the AutoMecado. It was the only store you could use, and it also was more expensive than other options. The up shot was that the trial run only lasted a couple of years.
