Hello it's been a long time since I posted something here but I just had this thought I want to share, so I was discussing with a friend about how the technology it's gradually hitting a point of "diminishing return" which it's basically a moment when future improvement on a certain area becomes slow and it's hardly noticiable. This especially affects companies that make profit selling products tha thrive trough innovation like tv's, smarthphones, computers, etc.
One example of a technology that is recently hitting a wall is screen resolutions, for a regular user 1080p is the wall for smartphones and 4k is for computers and tv, so in this way in about 5/10 years screen resolution will not be a deciding factor when buying a computer/tv/smartphone.
One more subtle example is videogames, improving graphics is becoming not whorth the effort, having better models implies a lot of work which is a lot of money and this doesn't guarantee profits, even that graphics no longer have that mindblowing factor that they used to have. We already experienced this effect with PS3/Xbox vs PS4/Xbox One.
So in this way imagine a future in about 10/15 years when you have a computer that has a 4k resolution, 8TB SSD, a battery life of 1 week, and the capacity to run any recent and future games (because nobody cares about better graphics), what would motivate to buy the next computer?
This also will apply to other types of industries, let's say in 20 years they invent a cheap car that works with water and last for like 50 years. What would you buy when you already have a godly computer, smartphone, car, etc.?
In conclusion I think that all the advances in technology will sink a lot of industries because their products are to "good" and I belive it will be in at most in the next 50 years but my guess is for the next 20 years.
