In terms of "is it worth it?" it is. Arabic is spoken by around 400 million people, with many L2 speakers. Muslims speak Arabic as their liturgical language. The complicated thing is that Arabic contains several dialects, some of which are incomprehensible to speakers of other dialects (e.g an Egyptian and a Moroccan or a Jordanian and an Algerian). The NA varieties (Algerian, Moroccan, Libyan, and Tunisian) are challenging to understand for speakers of other dialects. So, in addition to learning the formal language (MSA - Modern Standard Arabic), you would have to learn a dialect later (MSA is used on TV, news, essays, magazines, official papers, and so on), and you would have to choose a dialect from those available.
Yes, Arabic is worthwhile to study in any scenario. It all depends on how driven and dedicated you are and how much time you can set up for it. SayDhad is the perfect Arabic tutoring platform if you want to learn this language passionately.
