Whether you like it or not, it's called 'progression'.
If we were to go back in time several hundred years, we wouldn't be understood using our modern English. And vise versa.
The English language is very much alive and is recognised as THE International business language so I think it's here to stay.
To emphasise my point of 'progression', try looking for these now seldom used English words.
