Isn't the opposite true? A lot of "younger" developers are stuck disliking anything older than 2010 because it's not "new". Not because it's slower, or creates a bad experience for the customer, but because it's not new. If it's not faster, and doesn't provide a competitive advantage (I'm talking about real competition, not the pseudo-competitive market of "hire all the developers by dangling shiny new tech in front of them"), then what's the point? (There are certainly use cases where new approaches make sense, but that doesn't mean they become the new defaults)
