In computing industry, there's little pressure for weeding out "not better" new things. Unix is a great proof of that. Solutions survive on basis of popularity, not technical soundness, and many things get continuously forgotten and reinvented a decade later.
Often for good reasons! In my career, I've seen the pendulum swing from storage on every device, to diskless devices sucking from the network, back to storage. Many times. Never mind the philosophy folks quote; its about technology, or rather the relative speed/latency of network versus local storage. Its true in lots of things. Folks 'rediscover' messaging systems for redundancy and failover every 10 years or so.
IOW, your contention is true/truthy if you ignore the fact that there is a large selective pressure weeding out the "not better" new things.
