Of course Shelley's animated monstrous creature wasn't quite a cybernetic entity. That would require advanced computers, robotic parts or bionics & cybernetics.
However, if Ada_Lovelace had lived a few more decades, she might have realized that advanced digital devices could lead to AI & bionics, etc. Ada died in 1852 at almost 37.

About a century after the death of Mary Shelley and Ada Lovelace, things started to take off in the 1950s. https://www.computerhistory.org/timeline/1950
