I have read about Cameron’s dives and it seems like he truly has the explorer gene - that quality of a very few in a generation who work to go where no human has gone before, or only the very few. He completed just the second ever dive to Challenger Deep and he was the first human to solo dive to that depth.
I think those people are important, we need them to push the envelope for humanity - but at the same time they willingly take tremendous risk that they consider the partner of such ambition.
With OceanGate, it’s tourism not exploration- there just seems an element of foolishness. The whole thing seemed to lack the level of seriousness that accompanies the true explorers. But again, so what they didn’t deserve to die and no one should cheer it.
