The fact is that the competition is not in that sector alone, apart from the AI blockchain projects if you look at the market there are projects with the same aim mainly in advertising, gaming and finance you could see many projects popping up, but the team with the best project will thrive in the end, there is no guarantee than most of the projects will succeed in carrying out their plans, some will fade out eventually, i am not too keen on the projects you mentioned as i am mostly glued on to finance sector projects but i have invested a bit in Synapse and Singularity .
