This is a question that does not have a single answer. There will be many improvements to existing technologies and brand new technologies will be created. In the paragraphs below I will describe the technologies that have had major changes doing my career and will continue to change.
I have been working with computers for 57 years and the changes have been enormous. When I started the group of people was very small and dedicated to very specific tasks in a small number of computer languages. Today the WORLD works on different types of computers using many different computer languages, applications and human languages. Computers are being made smaller, faster, and cheaper for more people of the world.
Very important changes in the world of computers have allowed people rich and poor with varying degrees of computer knowledge to contribute to these changes. I have been working with Linux and open source programs for many years. Linux Operating Systems DVD can be bought for $5.95 and installed on as many computers as you and your friends have. Also, all of the software programs, browsers, applications, games, etc. are free not just free for 30days. Additional open source programs are free and available on the Internet that is used by half the people in the world.
Years ago people only developed code for money and couldn't believe there would be developers that would contribute their time to projects for free. Well the experts were proved wrong. Currently 31 million developers work projects on a code hosting site called GitHub. GitHub is the largest but there are others—SourceForge, Bitbucket, GitLab.
Most of these jobs are remote and you can bid on a project. People from all over the world work on various projects from their computer, etc. Some people work on these projects as a full time job others just need a little extra money.
Of course with the WORLD now involved in some form of computer activity there is the bad news. There are people out there looking to make money or fame by doing some form of illegal activity. So now there are new positions called Cyber Security to stop the illegal activity. The bad guys have a lot of time to think of new illegal activities so the Cyber Security teams have more than enough work to do. This is just one of the many new and improved technology positions that have been created.
Some of the biggest changes in the last 50 years have been the increase of computer memory, speed and data storage. One of the first computer languages I used was BASIC. A very English language that used very specific words to execute. Since the memory of the computer was very limited we were able to removed the spaces between words that were only needed for human readability. The data was stored on 1.44 MB floppy disks (711 of these floppy disks equals 1 Gigabyte).
Today the computer memory continues to grow larger and the data storage is larger beyond believe. Now they have what are called “Data Lakes” that store huge amounts of structured and unstructured data. Companies now don't throw ANY data away because they never know what questions will be asked in the future and which data will answer the questions.
