Artificial intelligence tools can now write software codes for humans, test them and also offer capabilities to fix them. However, the major question arises how humans can fully trust AI? Andrew Ng, co-founder of Google Brain and Coursera notes that despite AI taking over coding tasks, humans are still important. In his latest open letter, Ng explained how a series of feedback loops allow AI coding agents to write code, test it, fix bugs and continuously improve apps with minimal human intervention.
