Problem is AI has not proven to make a profit, nor prove it will do as claimed.
This exactly. AI is very very expensive in terms of compute power requirements and energy requirements. Until recently AI has not been something that has delivered capabilities you'd pay for - but that is changing. During the period it was like that it was all about getting people involved, drawing the crowd in. Now they need to make money, and we will see how the model actually pans out.
At my workplace we are integrating and paying for AI functionality as part of our usual tools (for example integrated into Microsoft M365 or some of our security tool automation). This stuff is all marginal cost (usually bundled in).
We are just about to spin up AI analysis tools for things related to economics - to the point where some actual data center grunt with significant GPU capability is required. This will be interesting, as we will see the true cost, and this will include peripheral costs such as securing such an environment against common AI risks.
From a security perspective AI is like the wild wild west at the moment.
