The video discusses the high cost of traditional customer service phone calls, which typically range from $10 to $20 per call. This cost is primarily due to the wages of the employees handling these calls. As a result, many companies make it difficult for customers to find their phone numbers, as the value of most customer interactions does not justify the expense. However, the introduction of AI in customer service has the potential to drastically reduce these costs, possibly by orders of magnitude. This reduction could lead to a significant increase in customer interactions, as companies would be more willing to encourage phone calls, knowing that the cost is minimal. The speaker envisions a future where websites prominently display phone numbers, inviting customers to call and engage in lengthy conversations without the concern of high costs.
