Real experts in any field may seem old-fashioned to hype-chasing non-experts. That's true of IT, project management, and many other fields.
Hype-chasing non-experts get overly excited about the latest trend and try to replace everything older with it. This causes two problems:
They don't benefit from older things -- a missed opportunity.
Their expectation of the new, hyped thing is more than that thing can offer -- it causes harm and uselessness.
We can visualize the non-expert usage pattern like this:
Real experts, on the other hand, rely on their knowledge and analysis instead of following trends and, therefore, have a usage pattern like this:
When a non-expert compares these two patterns of use, real experts may seem old-fashioned to them. This is not because the real expert is not adaptable enough to use the new things as much as the non-experts do, but because they want to benefit from everything with potential.
