Language is a medium to communicate your thoughts. What language was there to speak when god created this universe, but then human race invented millions of languages. Punjabi is one of those languages.
We are called punjabis just because we speak Punjabi right, a factor that makes us think that we are different from people who don't speak Punjabi. But has creation really made us different. We are closing ourselves in the name of Punjabi.
As our Punjabi language has so called grown and has taken the present shape and mould that it has, no guy e,g, a hindi speaking guy can understand what bhaiji is saying from Guru Granth sahib even though most of the words in GGS are very very close to Hindi or Other languages like Sanskrit, Farsi, Hindi, Brij etc. That is because the pronunciation has gone so different from other languages in just 300 years.
Then why worry about such form of languages which are just limiting us. Why not to be open then and take in all kind of pronunciations from different languages to make some big global language so that others can take advantage from what Guru has to offer and we could take advantage from wht they have to offer.
And this is actually happening, thanks to internet and technology.
Day is not far when Punjabi will just be a part of totality, a total language which will take care of all the languages including Punjabi. Everything is going to die and Punjabi too, but that will not be the end it will be a new beginning.
