It wasn't at all difficult to tell that comment was sarcasm.

The first clue was this line:

> I present to you: underwater data centers!

"I present to you" is clearly lighthearted, and then it gets rounded off with an exclamation mark.

And then this final sentence is also clearly sarcastm:

> We'd have to figure out the whole physics of it all, or maybe not, OpenAI can just ask ChatGPT for help!

I'd suggest to you that in situations where you think the meaning is unclear a better approach might be to assume the best rather than the worst. This is how we can extricate ourselves from the shoutfest that the world has become.
