It really is a complex project since we are talking about health and how to integrate it into the blockchain and have it access by millions of people wrong diagnoses or posted information can cost someone health.
Indeed it is a complex project but, given the pace of the tech world the timeline seems a bit off to me.
In the beginning I also was shocked actually, but I am not sure now. I mean, to see it realistic, good projects outside of crypto space also take several years to bring fully working platforms etc., at least for bigger ones. If I compare it with these, some years could be needed here too.
