In recent years, a growing number of countries have introduced computational thinking into the curriculum of compulsory education. In this text, firstly, we briefly analyze some of the problems generated by the absence of a consensus definition of computational thinking and a conceptual framework that guides its integration in the curriculum of the various stages, the relationship with other disciplines and with the digital competence, its evaluation, teacher training, etc. Secondly, some elements of the process followed in Spain to promote its inclusion in the curriculum are described, an example of "fast policy" similar to that of other countries, characterized by temporary compression and the indiscernible fusion of public and private interests. Finally, it is suggested that the discourse on computational thinking in education avoids the debate about how it contributes to the ends of compulsory education and about its previous assumptions and its political and economic implications.
