how humans don't mean what they say.

So funny! HaHa!, the chicken example.

Machines, as of present at least, are incapable to grab all the richness of cultures.

No, also not as of future. Machines are machines. Would machines grab the richness of cultures, they would not be machines but humans. LoL
There are simple machines and advanced ones.
A machine cannot be a human being. Only a human being can be a human being. All other beings are plant beings and animal/insect beings. Other apart from beings, are objects.

The question is how much strength we have to howl with them..

That is why being mortal is quite a good thing. Within ones lifetime to face drastic change happens more than once. If one is lucky, one can cope towards such and such progress, before one tires out. The moment one becomes too tired and does not want to face another challenge, one became already old enough to die. Is what I think. Of course, this is not a static thing and no rule but it's what I think about how often one can howl with wolves.

Seriously......! It happens. I have seen people believing on such ridiculous animations that made me question their sensibility

HaHa! Now, does not everyone thinks that of everyone else. So funny. It happens both ways, doesn't it? I caught myself numerous times in my life to have been all too gullible.
