Regarding your second question, you imply that it would be easier to automate the vegetable production than to automate livestock production. In fact, current dairy farms are in many ways more automated than crop farms.
Modern dairy farms feed, milk, vaccinate, etc. automatically--without any human intervention. The automated systems alert humans if an animal does not show up for food after some threshhold of time. Otherwise, it can even supply custom rations per animal, detect various ailments, track weight gain, monitor milk quality all by itself.
For the more general gist of your question--complete self-sufficiency on a single acre, that is more problematic to automate. Industrial farmers already automate a lot. They have automated machinery to re-level fields, plow fields, plant fields, and harvest fields, and irrigate. but those systems are largely practical only for large parcels. They operate on fields of, for example, 40 acres. And they are sufficiently expensive as to require many hundreds of acres to justify their cost. Also, they tend to be single purpose. They can only harvest corn, or only wheat. Planting a variety of crops within an acre would require a variety of automated tools. Think how different your equipment would have to be to harvest carrots as compared to barley.
I don't mean to say that it can't be done. But it would take a lot of work from where we are now.
Incidentally, your seedstock.com link is not impressive because it is "advanced." It's most impressive feature is its size. Hydroponic greenhouses tend to be more labor intensive (but have higher yields), although you could put the same attention into earth-grown crops if you chose.
