The death of calculator market?

[Hlib]

In my city with a population of more than one million inhabitants, there are about 5,000 students who study at local higher education institutions with international accreditation. At the moment, there are real engineers in the number of more than 150 units and about 200 highly qualified teachers of natural sciences for the entire city. I do not include primary schools, colleges, or higher education institutions without an international certificate in this data. It seems that you can effectively sell scientific calculators here. But...
At the same time, there are no graphic calculators anywhere in retail in my town. According to my data, in this city, you can actually sell no more than 50 expensive ($40+) graphic calculators per year (including illegal private transactions). I have been observing this situation in my region for the past 20 years.
On the other hand, last year in my city, several thousand Indian-made androids were officially sold in the price segment over $300 (not counting other categories), and the official revenues to the local budget from the production of cheap alcohol exceed the revenues from the sale of graphic calculators by at least a hundred thousand times, even for such a prosperous city as mine.
I am not concerned about the dying calculator market, because now, thanks to Internet technology, we can buy any calculator at any time, even without leaving the apartment.
