Of course, I’m familiar with the term and its origins. Obviously bacteria were not created by humans, but they were a runaway reaction that ended up covering the entire planet and even deep below the surface. The early microbes were things like hydrogenotrophs (etc) that could feed on non-biological matter, although limited compared to the hypothetical technological version.

I was just pointing out the oft-observed notion that the development life itself (especially simple life like bacteria) was a kind of grey go moment, but is being held in check by viruses.
