La factura invisible de la inteligencia artificial

In recent years, artificial intelligence (AI) has transitioned from being the exclusive domain of large labs and corporations to become an everyday tool for many. For less than the cost of a meal, anyone can now access capabilities that once seemed like science fiction. The democratisation of AI is undoubtedly a positive development.

However, this ease of access is also fostering a dangerous illusion: that AI is cheap. In reality, what has become cheap is individual access, not the business cost of utilising it. Many professionals are already employing AI tools independently, while numerous organisations still lack a clear strategy for integrating them into their processes.

Adoption is predominantly bottom-up, and this discrepancy explains why the price seems low while the true cost remains hidden. Companies typically budget for the direct costs of AI, such as licences, model consumption, infrastructure, or deployment services. They also estimate the indirect costs needed to embed AI into the organisation, including training, process adaptation, governance, cybersecurity, and maintenance.

These costs are visible and appear in budgets, even if quantifying them is not always easy. The trouble arises when we assume that the invoice ends there. Hidden costs silently pervade the entire organisation. There's the time spent reviewing responses, correcting errors, and validating results that appeared ready to use. There's also coordination between incompatible tools, duplication of solutions, loss of productivity during learning, constant human supervision, or technical debt left by improvised automations.

Even a functioning solution can generate additional costs: more controls, new security risks, greater dependence on specialists, and processes that nobody dares retire. Since none of these costs fully belong to a single department, they rarely appear in spreadsheets and are often undervalued. Even more challenging to measure is the opportunity cost.

Every euro, every work hour, and every strategic decision dedicated to an AI initiative diverts resources from elsewhere. The question is no longer which tasks can be automated, but where AI can generate real value. Choosing suitable use cases, deciding which processes to transform first, and concentrating efforts where there is a competitive advantage is a strategic decision.

One can deploy a lot of AI and yet achieve little value. All this is compounded by the speed of technological change. Models continuously improve, new capabilities emerge, and more efficient alternatives appear in the space of weeks. The consequence is that not only do technologies depreciate, but also the decisions and data that justified them.

Clients' habits change, markets evolve, and the patterns on which training models are based no longer represent reality before other technologies. There's also a cost that isn't often discussed: disentanglement. An organisation doesn't just adopt a tool; it builds processes, trains employees, develops automations, and integrates applications around a specific platform.

When a superior solution emerges, changing it involves retraining, re-building integrations, and acknowledging that part of the invested investment has lost value. All this forms the true total cost of ownership of AI. A cost that goes far beyond licences and includes indirect, hidden, opportunity, disentanglement costs, and technological obsolescence that forces continuous revision of decisions that only a few months ago seemed sound.

Democratising AI has lowered the entry barrier. However, it hasn't reduced the complexity of making the right decisions. Because the most important invoice likely never arrives in the mail.
