It’s essentially about if your skills are “Turing complete”. If you know only Java, you may not be able to build an app that requires assembly tier efficiency but you can do it. With vibe coding you just have to hope and pray. It’s not really a skill. Your skills are not Turing complete.

So vibe coding won't be sufficient to replace a skilled Java developer, and won't obsolete that skill, and if there aren't alternatives that more completely replaces a skilled Java developer, this then isn't a relevant comparison.
