"Cloud" providers often hide how their systems work, their real intentions, their vision for the future and our place in that future.
For example Amazon is building a surveillance network, training its "Rekognition" on user data. Microsoft has built an "Azure", as data is the new asset and there's a big race for data in the world now. The company that has data, has a better position on the market. Customer data have leaked from Azure several times, as a result of flaws in design of their object storage system. This means they are not motivated to invest into security of user data.
But lets try to imagine, what may happen during next decades and in what directions tech sector will perform its activity during next 10-20 and maybe 30 years.
In 1997 Peter Schwartz and Peter Leyden have formulated 5 waves of technology.
When we download a file from Dropbox or "G" Drive, it travels thousands of kilometers to our device. Modern phones produce 1 GB of video per minute and data size grows very fast. At the same "cloud" providers keep limiting bandwidth. But even if they don't limit the speed, it depends on the physical distance between the file storage and your device. I think it will not be practical to build mainframes, such as "cloud" in future, as data size will be too large to transfer from far away.
The next 3 technological sectors: Biotechnology, affecting food production, Nanotechnology, opening new ways in the Health Care and Alternative energy, as far as I'm aware, use "AI" algorithms, that are trained on large data sets.
Those data sets have to be stored securely, as they represent a trade secret. My assumption is that data-based companies need to store such data locally, not in "clouds".
I predict that governments will start producing working laws, for regulating the technological sector, as economies become more and more dependent on technology. Legislation will force large Internet companies to offer their users a choice of data storage.
Tim Berners-Lee, an "inventor" of the World Wide Web, has created Solid Project already.
We, in order, are providing the most efficient access to “cloud” storage service, with the difference that you can choose the location of your server and who should manage it.
