Automation has already been heavily cutting at the so-called low-skill jobs starting from Industrial Revolution. Or by some definition, from the Agricultural one somewhat earlier.
But the examples of the gardener and cook that were in your citation are actually quite good, I admit.
The secret to automating repetitive jobs is often finding a different way to do it that provides a similar output, but is more amenable to machinery. A sewing machine doesn't sew at all like most humans, a dishwasher doesn't wash like you would with a sponge etc.
Gardening is hard to automate, but harvesting of somethings (grains, mostly) is heavily automated. Cooking is more amenable to augmentation than full automation, but there are exceptions mostly around processed foods.
