I think it is, because the entire thing reads as someone with very little life experience. If they've truly been in the industry 20 years they would have experienced plenty of similar career anxieties - the .com boom/bust, outsourcing, and global financial crises.
This has me far more concerned, as I went into detail in another comment in this thread.
Much of what I see in this thread feels like platitude-driven myopia, which brings to mind the famous Upton Sinclair quote "It is difficult to get a man to understand something, when his salary depends on his not understanding it"
So, it is "Your salary depends on your ability to convince others that you can not be replaced." basically.
Everyone is talking about "that other developer who has less experience, they will be the one to be replaced". The more I hear, the more suspicious it gets to me. Like everyone is so sure of themselves.
