interesting project. I hope they have collected all the necessary funds to fully implement it and soon we will be able to see working prototypes.
But no one knows when this will happen. we can only wait at the moment. But I should note the very idea of the project is excellent.
now we do not see anything and therefore it will be quite difficult to draw conclusions. and you have to understand that all these people can be scammers. still, there is such a possibility.
