  The recently reported experimental results claiming "quantum supremacy"
achieved by Google quantum device are critically discussed. The Google team
constructed a quantum chaotic system based on Josephson junction technology
which cannot be reliably simulated by the present day supercomputers. However,
the similar "supremacy" can be realized for properly designed micro-mechanical
devices, like periodically forced Duffing oscillator, using the available
technology of quartz clocks. It is also reminded that classical and quantum
chaotic systems behave in a similar way. Therefore, in this case, one should
speak rather about the "analog supremacy" than "quantum supremacy" what means
that even now mechanical analog computers can outperform supercomputers when
the computational task can be reduced to sampling of ergodic measures generated
by chaotic systems.
