Ambient Intelligence (AmI), i.e. intelligent environment – a technological project which has a chance to be introduced in the next 10–20 years – is supposed to be an interactive network of miniature electronic devices, communicators and everyday objects “immersed” in the environment. While the “technical” side of this phenomenon can be to a large extent imagined and predicted, further consequences of the development of the “intelligent environment” exceed our contemporary cognitive horizon. The article presents in brief main characteristics of the AmI, hopes relating to it (immense possibilities as far as practical improvements, safety and the protection of health are concerned) as well as the most important spheres of threats (privacy, identity, safety, trust, exclusion). In the next part of the text, referring to, among other things, the analysis proposed by Cecile K.M. Crutzen, crucial lacks in the mainstream of the reflection on the intelligent environment are being pointed at. Ethical requirements – as shown by already mentioned critique of the AmI – point to the need for transparency, “unhandiness” of the system, therefore, are aimed at that which is supposed to be the greatest advantage of the AmI: its immersion into environment and “invisibility”.
