The hidden cost of an artificial intelligence we do not understand
An opinion piece by VigÍA warns that companies calculate the cost of implementing artificial intelligence but not the cost of a wrong report, a leak of confidential information or a decision no one can explain. It cites a September 2026 OpenAI study of 1,000 SME managers in Spain: 39% lack a formal AI use policy and 26% cite lack of training. In an experiment with 758 Boston Consulting Group consultants, access to GPT-4 sped up certain tasks by 25%, but in a strategy test the group without AI answered correctly 84.5% of the time versus 70.6% with AI.

- 39% of the Spanish SMEs surveyed by OpenAI lack a formal AI use policy and 26% see lack of training as a barrier
- In the experiment with 758 BCG consultants, GPT-4 sped up certain tasks by 25%, but the group with AI scored lower on a strategy test: 70.6% versus 84.5%
- The text argues that AI investment must come with training, review of results and human responsibility
