Bots might have significant limits on how helpful they are, such as tech support bots you might have had frustrating experiences with on various websites.
Yes, I agree with this sentiment, recently my I was trying to returning something, I had go through so many loopholes and ask the Chat Bot the same question several times that it was so tiring, wished I just could've called someone. In the end the Bot didn't understand and I ended up finding the email of the customer service. While, bots are useful at times, this shows that some support bots on websites still need help and can't fully capture a real person for customer service.
