Is the AI hype bubble in cybersecurity deflating?

Artificial intelligence has been touted as the "next big thing in cyber" for some time, even though the concept is as old as the first email viruses. The clamour around the technology, which started in late 2015 / early 2016, was quickly amplified as it became a tool in heavy use with analysts, sales teams and marketers. AI adoption continues to accelerate, and according to Capgemini's Reinventing Cybersecurity with Artificial Intelligence report, 48 per cent of respondents said budgets for AI in cybersecurity will increase by an average of 29 per cent in 2020. However, it's important to note that potentially only a few vendors exist with the R&D budget to pour tens or hundreds of billions of dollars required into building pure AI for cybersecurity. Typically, instead of AI, what people are usually talking about when it comes to uses in cybersecurity is machine learning and its associated subfields: Supervised, Unsupervised, Reinforcement and Deep Learning.
