  Sapir, Birget and Rips showed how to construct groups from Turing machines.
To achieve such a construction they introduced the notion of S-machine. Then
considering a simplified S-machine Sapir and Olshanskii showed how to construct
a group such that each of its asymptotic cone is non-simply connected. Still
using the notion S-machine, they constructed a group with two asymptotic cone
non-homeomorphic. In this paper we show that each asymptotic cone of a group
constructed following the whole method of Sapir, Birget and Rips is not simply
connected.
