> I just don't understand what's even intended by this.

I might be misinterpreting, but according to the landing page, this is the intention:

> Personal Computer gives Perplexity Computer and the Comet Assistant always-on, local access to your machine's files, apps, and sessions through a continuously running compact desktop.

> It's a persistent digital proxy of you. Controllable from any device, anywhere.

That being said, the grandeur and bombastic language also seems fitting for something less sinister, like an even worse version of MS Recall maybe? Combined with, let's say... agents!

That's it! You Personal Computer is your agent and not only may act on your behalf, it also communicates your preferences and intentions.

Futuristic, right?
