This article aims to formalize a moral dilemma regarding the frequency, measurement, and conditions that must determine the decision to refurbish or replace the technological base on which we deploy an activity or set of actions. It will be called the dilemma of technological otherness, since it involves an ethos that calls for openness to another possible set of technologies. It is a dilemma, firstly, because the potential deployment of an action would always confront two realities: the action through the current technological base, or a new one that can be thought out and implemented. It is also a dilemma because its solution responds to specific conditions of the context in which the dilemma appears (a company facing bankruptcy would face the dilemma differently than an academic corporation that wants to improve the dissemination of its knowledge among citizens). The article will attempt to substantiate the dilemma by resorting to: 1) the hypothesis of technological determinism, 2) the theory of cognitive biases, and 3) the concept of alterity (otherness). The cognitive bias, taken from psychology, will allow us to support, from an empirical point of view, a "soft" technological determinism, according to which technology presupposes a determination in the form of a bias, but which can be countered by developing evasion strategies, so that the moral responsibility of the subject facing a set or collection of technologies would be indefectible in any case.
