  We consider some implications of the much-discussed circumstellar habitable
zones around M-dwarf stars for the conventionally understood radio SETI. We
argue that the flaring nature of these stars would further adversely impact
local development of radio communication and that, therefore, their
circumstellar habitable zones should be preferentially studied by other
methods. This is a clear example how diversity of astrobiological habitats is
introducing contingency into the cultural evolution, thus undermining the
universality of cultural convergence as one of the major premises of the
traditional SETI. This is yet another example of how specifics of the physical
environment strongly shape cultural evolution taken in the broadest, most
inclusive sense.
