No, the blinking cursor is a feature, not a bug. Alec Watons over at Technology Connections has a much better argument for this than I could ever hope to muster, so I'll just hand it over to him:
Which is to say that the host and OP agree lack of discoverability is a problem (Watons just views it as maliciously inserted problem). And so your "No" involves a bit of misrepresentation...
That's not the message at all. The message is that the problem with social media is that it feeds you content without any prompting, and so it turns the user into a purely passive consumer and robs them of their agency. There's plenty of discoverability in social media. The problem is you don't have to use it, and so people don't. A blinking cursor forces you to take the wheel.
For a novice user or someone who is not from the domain - it can be challenging because they may not know where to start.
There is so much that can be done in this space by fully leaning into the AI. It can for example figure out the user’s level and offer varying levels of guidance and help.
