Yeah, booking a flight is only difficult because I make it difficult by deciding about how I feel about cost versus layovers versus time of departure/arrival.
For grocery shopping, I'm very specific in what I want, and it's easiest just to pick them specifically. For a lot, I'd rather just go in person to the store to look over things. In fact, whenever I spend money I'm pretty specific in what I want and I don't want something to "improve" things by letting me be more vague.
As a point of comparison, fast food ordering. Apps and Kiosks were actually a step up for me, because it was easier and quicker for me to see what the options are and select precisely what I want. AI order taking would be a huge step backwards from there. Even when ordering from waitstaff at a restauraunt, I always like to have my finger clearly pointing to the menu for what I want to order.
In short, you choose getting laid.
