The chatbot phenomenon gained momentum in the early 
2010s, with banks deploying AI-powered solutions that could handle FAQs and basic transactions. A notable advancement came with the introduction of 
Natural Language Processing (NLP). This technology enabled chatbots to understand & respond to customer inquiries in a more human-like manner. Major players such as 
Bank of America unveiled 
Erica, their AI virtual assistant, which assists customers in managing their accounts, offering personalized financial advice based on spending habits.
Smarter chatbots, like 
Cortana and 
Siri, also influenced user expectations. Customers now started desiring intelligent & conversational interactions rather than robotic responses. According to a 
survey, 
90% of companies reported an increase in customer satisfaction due to AI implementation.
