Explain evolution of RPA. give in pont form

Sure, here is the evolution of Robotic Process Automation (RPA) in point form:

1. Traditional Automation: This was the initial phase of automation where simple tasks were automated using basic scripts and macros.

2. Screen Scraping: In this phase, software was developed to capture and interpret the user interface of a computer. This was a step up from traditional automation but was still limited in its capabilities.

3. Workflow Automation: This was the next phase where the automation of business processes was done through the use of software algorithms. This allowed for more complex tasks to be automated.

4. Artificial Intelligence: With the advent of AI, automation took a giant leap forward. AI allowed for the automation of tasks that required cognitive abilities like decision making, learning from past data, etc.

5. Robotic Process Automation: This is the current phase of automation where software robots or 'bots' are used to automate high-volume, repeatable tasks that previously required humans to perform. These tasks can include queries, calculations, and maintenance of records and transactions.

6. Cognitive Automation: This is the future of RPA where the bots will not only be able to perform tasks but also understand and learn from them. They will be able to handle unstructured data, understand natural language, and make decisions based on complex algorithms.
