Ordering automation is there with order-and-pickup apps like doordash and instacart, it's just they charge a fee that costs more than doing answering the phone typically, which is why restaurant owners tend not to like them. Also those kind of seat yourself / serve yourself places exist, they're called fast food typically. Look at mcdonalds, chipotle or subway for example. That setup is actually very old, from the time before computers. Places that serve alcohol like waiters although, because they are essentially alcohol salesmen that boost sales, and alcohol are big profit drivers for restaurants.
