It's been argued both ways for a hundred and eleven years now, but my understanding of the current historical consensus is that they weren't doing anything especially unusual for ocean liners of the day, either in design or in operation, and indeed had altered course further south in response to iceberg warnings received by radio on the 14th.

It's considered to be true that the prioritization of on-time arrival and the belief that the ships of the day were too well designed to founder contributed to the disaster, but rather than representing unique hubris on the part of Titanic's builders and captain, these are understood to have been common throughout the passenger shipping industry of the day.

Uh, the Titanic ran into an gigantic piece of ice which caused it to sink, the previous quote is the context for that.

This submarine likely decompressed, killing the CEO and I believe 3 rich tourists because they didn't believe they needed to check the health of their submersible, firing the people that raised security concerns.

I think it's safe to say that both captains were full of hubris
