What is the definition of architecture?

The architect word defined from the ancient Greek word arkhitekton (arkhi-, chief + tekton, builder) or the chief Brick maker. The idea is somebody who is responsible for the construction of living spaces. So my idea is Are we responsible for the living spaces only???.
Because in my university whenever the design is not brick and masonry the idea is this is not architecture, architecture is brick and solids why don’t you go to the mechanical engineering department. But accidently when we go to the mechanical engineering department they are still playing with the size of the piston for the suitable engine. So my biggest question is why do we need to define what we can what we are really capable of why can we imagine things which are not related to the architecture. Leonardo da Vinci was an artist luckily who didn’t go to a university had experiment with lot more thing. What if the society had defined in his era that the artist’s job is to do only oil painting so then?????
Geoffrey bawa is not an architect but he was introduced to the architecture later, just like that we can incarnate and experiment with new ideas... we a should have the enough freedom to understand the threshold of the subject that The young ideas cant simple if they are simple they are not fresh ideas. Because we can image better things than the old people. They are not ready to realize it they think that old books say the newest things in the world and they up to the date to challenge to the youths. But sometimes we are making solution from our own dreams. How can they dreams without have new exposure.
That’s why I made this question what they don’t understand is not architecture…. May be easy to answer and easy to argue with somebody this is not architecture this is technology. But if you ask from the ancient Hindu valley civilization working guy what architecture…is.??? Oh… the architecture is Brick making the architect is the chief of Brick maker….. That can be better answer for me because at that time the architect’s job is only to create brick and solid things for the construction. Ok may be the civilization hasn’t developed us are just talking about big Ideas that we have a concept wow that’s a folly for me………. Somebody saying to me Hah hah haaa I have concept
Well I think according to them the architect’s job is to create story and tell stories to people and make fancy world in front of them. By all mean I agree because we should give what the society demand from us may be demand is a story teller not evens a brick builder. That’s ok sooner or later when the society demand a creator from us then we should tell them we can not supply what you want because the machine produce only story tellers at the moment..
