Why hasn't the traditional short message improved for more than ten years?

why hasn't the traditional short message improved for more than ten years?

hello, the progress of a technology is driven by many aspects.

it is determined by many aspects, including the persistence of demand, the investment of funds, the development trend of technology and the rising space of SMS itself.

There is still a demand for short messages in recent years, but the business volume is dropping sharply every year because of the rise of mobile Internet.

the decline in business volume leads to the decrease in the income of enterprises engaged in this business, so the R&D funds invested in this technology will definitely decrease, and the investment in R&D is to increase income.

It is not accurate to say that there has been no progress in the past ten years. SMS has made some progress, but it can't be compared with the progress speed of mobile Internet.

If the answer can help you, please give me the best one. Yours is definitely my motivation. Thank you!
