The article claims that the technology was made obsolete by other methods "made possible by a more advanced understanding of diving physiology and more complex mixtures of breathing gases." The technology was indeed largely replaced by others (although marine biologists have employed similar underwater houses in the US Virgin Islands and elsewhere (many described here: Underwater habitat). But afaik, it has nothing to do with physiology or breathing gas mixtures, and everything to do with the economics. But I have no citations, so say that would be original research (not that the original article has a citation for this, so I've tagged that). If someone knows real information about this, it could be added here, although maybe it isn't even needed here and should be in the Underwater habitat article.
