I seem to notice this particularly often with a subset of developers. People who have a very strong "who moved my cheese" mindset. They are used to doing things a certain way. An approach that is simple to understand, but takes a very long time to get anything done. Ie, writing vanilla HTML without any frameworks. Besides, they aren't the ones paying for a team of developers, so they don't really see a downside in spending 1 month to do something that could have been done in a week.
And then all of a sudden, everything starts changing. Nobody wants to hire a vanilla JS/HTML developer anymore, they want react developers. And these react kiddies are able to put together a webapp that looks so much nicer, has more functionality, and they are able to do it in less time.
They decide to try learning react, but find themselves with a tough problem they haven't dealt with in a while - being outside their comfort zone. They are so used to doing things a certain way. They know exactly how to do it. They can do it blindfolded. And all of a sudden, they find themselves having to change everything up. Overnight, they go from feeling like experts to feeling like novices. And they hate it.
If they pushed through it, they would eventually gain mastery over it and learn to evaluate this new technology fairly on its merits. But they never do master this new technology. Feeling like a newbie is too psychologically painful. But they also recognize how much of a disadvantage they are at by not riding this wave that is taking over the industry. And so, rather than expressing indifference or acknowledging personal taste, they lash out with tremendous resentment and anger.
> No, I will not be polite and call it something else because it is truly sheer stupidity. In the so-called modern day it's like everyone - except a few - has dropped their brain on the floor. Has everyone except the "unix greybeards" gone mad!?
I get it. Change is scary. But it gets even scarier when you try to resist it instead of embracing it.
