I am at the end of the third decade, soon entering the 4th. I find it easier with the time. This is because with the experience, I can directly zero on the fundamentals of the new technology popping up and quickly see if this is just marketing or more a breakthrough.

Also, we have less diversity now, every new tech getting momentum is quickly defacto standardizing. Look at the way we run LLMs now, tons of models, 5 lines of Python, within 2 years, everything kind of standardized. You can now quickly pick up the subject (ironically, the LLM will help you there) and run with it.

It is way harder for young people, because of this FOMO, they try everything and nothing, they copy/paste what "God" GPT told them and have no understanding of how things are working in the background. For them to learn "through the stack", without experience, with the new big thing coming out every week but without the ability to judge, it is very hard. I am happy that my first website was static and cgi-bin was still a thing, happy that I learnt how to get my Fortran code to run fast on an multi-core system (yes, Sun stuff), that I was able to build relatively slowly my experience.
