This is indeed far too profound.
By the way, six years ago I built a huge desktop machine at home.
It was capable of supporting multiple graphics cards, but I only installed one of the cheapest ones just for basic display output.
About three years ago, I even removed that cheap GPU, because as a network server, I could connect to it via SSH — no need for a monitor at all.
Around eight months ago, I deployed a home AI assistant on it (ollama + open-webui + DeepSeek R1 14B).
It barely works, but I honestly couldn’t imagine what to use it for — after all, ChatGPT is already great and convenient enough for me.
