I was simply stating that blanket statements that "more ram is better". You do know that there are some production studios that are working on 8K or even 16K footage right? Yes, more RAM will be better in those scenarios. I have build a couple of servers at work that have 4TB of RAM and 128 CPU cores because we NEED that performance for one of our clients.
Where did I say 8GB of RAM is fine for EVERY SINGLE USE CASE IN EXISTENCE? I did not. I was saying blanket statements that "More ram is better" is not a good thing to say. You need to weigh what the person needs. In this case, the original poster is only doing HD video editing, so 8GB is fine for him. Not "More RAM is better".
So please, tell me where I made the argument that 8GB of RAM is useful for every possible workload in existence. If a production studio only does HD video, then yes 8GB of RAM is all that is required. If you go in to 16K video or multiple 8K streams, then yes obviously more RAM is needed. Just like if you want to have dozens of Virtual Machines (which explains the 4TB of RAM we have on a couple of servers between program VM, database VM and many other virtual machines from Active Directory to DNS.
