To me it is about Hardware, Software, and the Internet. I started IT a bit later during it’s boom period. When I was in school, right to repair was still huge. Now everything is “It’s cheaper to replace than repair”. Servers were all in house and software was installed on each individual system, now everything is moving towards cloud/network based. IOT has also destroyed the need for a lot of IT professionals in my opinion, because a complicated day setup of getting someone online, wiring a setup, or hooking up a security camera system can now be done by anyone just by purchasing the right item online (typically due to wifi eliminating cables and smartphones acting as installation devices).
Now lets get to software. Patching is still a thing, but is WAY more consistent. Subscription models have taken over which is destroying budgets, but also helping with patching and upgrading in a way since most applications force new versions instead of us having to read millions of release notes and figuring out if the program will even still run with each passing update. Also in a programming sense, there are way too many programming languages and SDKs in the world right now and any breakthrough program you can think of has already been thought of.
The internet is also a huge catalyst. Now Ransomware and Trojans have taken over viruses just cripped computers. Datamining is the way of earning money instead of making good products that encourage repeat business. This has made IT Consulting positions less needed too since a product can be bought once and ran with for a decade instead of going back to the well each time a new version of something comes out.
IT is massively different. Not so much bad, but I was just talking about this with someone over the weekend; when I was in high school and college, we were lead to believe that IT jobs were all Bill Gates’ money positions. It was up there with Doctors and Lawyers. By the time I entered the market, IT pros were a dime a dozen and most companies didn’t want to pay newbies more than 32k which was an insult for all the education and certifications it took to get to that point.
If you watch old media from the 90s and even early 2000s, you will see anyone who knew photoshop, data recovery, or web design as a god amongst men, now it is your typical 8 year old. The supply and demand for it has definitely changed and so has the way that the work is done. The knowledge aspect will always be there for us, but the type of knowledge is forever changing.
What was once general IT is now Network Administrator, Cyber Security Analyst, and Director of Technology.
I think I rambled way too much and left out a lot of details to strengthen my point, but there is also a lot of content for people to feed off of in this brain dump of mine.
