You're missing context and/or didn't read OP's comment. He said "will" with regards to reaching AGI. He said "only AGI can find" with regards to profit. It was the latter that this thread was addressing.
Sure, they phrased it as "they will reach AGI," but that's clearly tongue-in-cheek...the underlying idea is "they better reach AGI, because that's the only way they could make money." So my comment ("necessary, not sufficient") was just pointing out that even if AGI is required for profitability, it doesn't mean they'll actually get there or succeed once they do, and that the original comment was perfectly compatible with the idea that not every business reaches profitability.
Yeah, that's what I was going for.
