We can't be "the most comfortable" generation because we don't know what will be tomorrow. Maybe people will be living in a virtual universe very soon? Or maybe Mars will be much more comfortable?
The questions that you are considering arise in the minds of people for a very long time. Comfort and happiness look different in the eyes of different people (and different generations).
By "most comfortable" I mean all the facilities and comforts of life we have thanks to tech.
