Modern business is full of unpredictability.

"We know only two things about the future: It cannot be known, and it will be different from what exists now and from what we expect." ── Peter Drucker *1 In the past, businesses would classify situations into categories and handle unpredictable circumstances by considering contingencies in advance for each category. However, fluctuations in demand and prices as well as diversification of individual preferences are just happening at an increasingly rapid pace. As business activity crosses borders, businesses also face differences in national and regional cultures and customs. Attempting to accurately classify all of these would result in an overwhelming number of categories. And because envisioning all kinds of situations in advance is theoretically impossible, a business would need to constantly update its classifications and approaches, requiring a great deal of effort and cost That is where AI comes in. But existing AI has its limits. The way to change this state of affairs is through AI (artificial intelligence). There are already several types of AI being used today, but each of these is merely limited to a specific application.
