The article is written in a very dreamy tone and contains very little substantial information. It firmly assures that "Proteus will be" such and such, as if they are making the finishing touches already, yet "Proteus is still in the concept phase". "Fabien is raising $135 million" (which, TBH, seems quite a conservative estimate for this project on the one hand, and on the other is a pretty huge investment for something that doesn't have any ROI projections attached), but there's no discussion about what else except for his surname this Fabien guy actually has to have any chances to succeed.
So, yeah, I would prefer if journalist learned to provide something more factual and informative in their stories, instead of telling me how cool deep-sea exploration is. I know it's cool, alright? I don't know if a project like that can actually happen in the observable future.
