There are some areas in technology that have reached maturity and are at the point of being good enough. Take JPEG image compression for example. This old technology is used on websites everywhere to compress images. There is a newer JPEG2000 format which is technically superior. However, this superior technology has seen very little adoption on websites. Internet speeds are so fast that the benefits (webpages loading slightly faster) aren’t important enough for webmasters to switch.
For some shareholders, there may be a disappointing future ahead. Once the demand for more computing power stops, there is no longer room to create value with newer technology. Often what happens is that mainstream consumer demand goes away first. This can devastate the business model of companies developing new technology as it can only be sold on a smaller scale to niche markets.
