Playing with the supposedly GPT3 quality LLaMA and Alpaca models really highlights how there is a quality level beyond which these things become suddenly useful.
The responses from Alpaca are "mostly" sort of there, but unreliable in my experience.
ChatGPT is just so much more confidence inspiring to use, because it is just the other side of the "mostly coherent sentences, but not quite what I wanted" to "more or less what I wanted, most of the time".
Want to know when I post new content to my blog? It's a simple as registering for free to an RSS aggregator (Feedly, NewsBlur, Inoreader, …) and adding www.ff00aa.com to your feeds (or www.garoo.net if you want to subscribe to all my topics). We don't need newsletters, and we don't need Twitter; RSS still exists.
