Let me try.
Example 1:
Before 2-3 years AI was there but wasn't that much of a strong buzzword as Web3 and Metaverse and others.
Once the Gen AI came into the picture, AI became the strongest buzzword however it's not just a buzzword.
If you are a techie then you need to know how to use Gen AI and also have at least high level understanding of how Gen AI works.
Example 2:
A few years back for Test Automation Engineers it was enough to know one area (Web UI/Mobile UI/API) from the automation perspective.
While the architects/leads and senior engineers had been suggesting to leverage API Automation as much as possible, it was not always accepted by the clients.
Suddenly people realised the value of API Automation and since then it has become a must have skill.
So the engineers who didn't know it had to learn it and those who didn't learn it till now are struggling to get new jobs/projects.
To summarise, every once in a while a real big change will come in terms of what is expected of you and if you aren't able to catch up with it in a timely manner, you will be in a tough position.
So if you have that kind of mindset that once you get your first job then you are set and don't need to hustle or learn things then it's going to trouble you later.
It may sound too big or too tough to do, in reality it's just about having acceptance about the need of upskilling and doing it in a timely and disciplined manner.
