People quit Google Search to avoid "search-optimized junk" just to use AIs that answer using "Search" lol. Look closer at the sources your AI answers give you. They're not always pretty.
I wonder how they're going to repay their MBA tuition. Typically a tenure in consulting or high finance would pay for this. Perhaps some don't have this burden, but for many I assume tuition is paid in large part via student debt.
Are they planning to pay themselves large salaries from the get-go? Quite a culture to start a business on...
Having thought about this idea in the past, I can say that one of the difficulty lies in the fact that the market "seems" really large, when in fact, you can only address a limited portion of it. People have different tastes and goals in what they want to accomplish in a "trip", and because the market seems so vast and large, the idea tends to gravitate towards the middle ground. You might satisfy a wide array of people, but none of them will really "love" your product. So rather than daily usage, I think the problem is of segmentation first (and competition, etc following...).
