The first two tasks could be easily done by asking ChatGPT to write a script for you. Scraping a website can be a bit more tricky. Still, I don't see why you have to rely on "computer use" for these tasks -- there are much more efficient and reliable approaches to the tasks.
There's a gigantic area of productivity improvement around repetitive actions that aren't easily scriptable or no scripting interface exists. But where an AI assistant that interfaces with your screen, pointer and keyboard would be a huge help.
That's about manually setting up agents, that run on a server, that seem to interact largely with the web (from the examples).
I'm talking about not manually setting up anything -- I'm talking about an AI that simply observes the repetitive actions you're taking on your computer, infers patterns from them, and then offers to take over and finish the job.
I think we should start with something simple, repeatable, and does little to no harm if/when things go wrong.
Edit: repetitive -> repeatable
People have tons of workflows that involve a lot of clicks and typing in response to data that are too difficult or one-off to automate with fragile macros.
But if my computer can quickly realize that I'm deleting every odd-numbered page of a PDF, or renaming every file to add a prefix, or following each link on a website and saving an image... and then just instantly automate the next 100 times... that's going to be huge!
