As technology progresses and society moves further into the digital age, the volume of data that needs to be processed and distributed is increasing at a rapid rate. As if that weren't enough, the data is becoming increasingly complex as well, with some modern software systems consisting of millions of lines of code. Their maintenance requires huge data centers with large teams of software developers, and they consume a ton of energy and financial resources. To mitigate this industry-wide problem, data science experts from Lancaster University have developed an artificially intelligent computer software system that can rapidly self-assemble itself into the most efficient form without human input. The system is called REx, and it uses machine learning to perform.
