Historically, most primitive languages were based on indexes, icons, and symbols. The majority of proto-languages, which no longer exist, transitioned into symbolic languages (phonographic languages). Chinese remains a unique case as the only remaining icon language (ideographic language) still utilizing iconic methods. All other languages have transformed into phonetic languages. The Himalayan theory offers an explanation for this phenomenon, though further research is needed to consider additional factors. Assuming no obstacles like the Himalayas, human languages might have universally evolved from icon languages to symbolic languages. Presently, with advanced technology, geographical barriers no longer impede language changes, allowing for rapid and frequent transformations. However, the historical impact of geographical factors over thousands of years on current human languages cannot be overlooked. Navigating the challenges of the future’s linguistic development and change poses a considerable task for mankind.
