I suppose her reason to assume we can't observe this is that evaporation takes extremely long time. For example, a solar mass black hole will take about 10^64 years to evaporate [1] (this is approximately 7 * 10^54 times the age of the universe). Note that astronomical black holes are heavier than the Sun, so take even longer to evaporate.

I suppose the micro black holes [2] might offer a glimmer of hope, but these objects are entirely hypothetical.

Creating a microscopic black hole is not completely out of our reach. https://arxiv.org/abs/0908.1803 discusses this topic a bit. If the assumptions there are not wrong, and climate change doesn't get us first, creating small black holes might be become possible an a couple of generations.
