Codex, a new AI technology, writes its own computer programmes. It was feared that such a technology could threaten the jobs of the programmers. However, the fear is unfounded. It is a tool to improve human productivity. It facilitates a coder’s job. Codex is built by OpenAI. OpenAI is prestigious research lab dedicated to AI.

Of late. the neural network has attracted attention. Machines, as we know, learn certain skills, by analysing huge amount of data. OpenAI researchers design neural networks that analyse vast amount of prose and recognise patterns in text. The network learned to predict the next word in the sequence. They could complete the thought with entire paragraphs. OpenAI has created GPT-3 which writes its own Twitter posts, speeches, poetry and news articles.

AI recognises voice commands, translates languages, identifies street signs and identifies pedestrians.
