&quot;Cook like an expert&quot;: There&#x27;s much more to cooking than just following steps. AR don&#x27;t help much preventing you to slice the onions instead of your fingers. The wrong temperature, an egg that is larger or smaller ... it&#x27;s timing and knowledge&#x2F;experience, not a rule book that makes a great dish.<p>Same for the car maintenance: Perhaps you could do it yourself and save a few bucks. Would you repair your breaks yourself with AR but no knowledge and understanding about cars and maintenance if the life of your children depends on these breaks?<p>Both scenarios might work for an expert or at least someone who knows the fundamentals, but not for an unprepared consumer.
