I can't entirely agree with the points mentioned in this article.
Yes, a chatbot is not ready to replace human support.
However, there are other areas where they show good results.
We have been helping customers with lead generation chatbots for the last four years.
What we have learnt is customers would instead engage with a chatbot than filling up lengthy forms. Because chatbot nudges users to give information.
Also in websites where you have a lot of information to convey, ex: banks, mortgages, etc. again chatbot makes sense. Because it helps give information that's selective to the customer. And they don't have to struggle through a lot of information presented to them at once.
We have customers who use our chatbot link directly on google ads.
We have also noticed our customers maturing over time and demanding more functionalities on the chatbots.
To summarize, no chatbots are not dead. They are only beginning. However, you need to narrow down on a specific problem and solve it.
