People also takes it a bit to far. Sure, RAM is cheap enough, but if your application requires 64GB of memory you may start having other issues.
We have customers who requires servers with 64GB+ memory, of single applications. This is running on VMs in VMWare. If a ESXi host crashes, you'd want VMWare to migrate your VM to another ESXi host, but that becomes somewhat tricky if you need to locate one with 64GB of available memory. Unless of cause you're way over-provisioned, which is actually pretty expensive. More realistically VMWare will start moving a ton of VMs around to put all those with little memory usage on other hosts, in an attempt to find 64GB for your VM. This takes time.
It can be difficult to explain to people that really this should look at their memory consumption, if nothing else to plan for fail-over.
