I said it two years ago already: An LLM is the perfect user interface.
The problem though: It will make it a lot easier to do harder things which will devaluate jobs.
These laymen presumably don't even know what a zip file is, so what are they going to prompt? Let's assume they even know in the first place that they could ask the LLM to "Open this file for me". They also presumably don't know what a filesystem is, or where their file is located within that filesystem. "Open this file that I just downloaded from my browser". They have a billion random zip files strewn across their downloads folder they never, ever clear, or as seems to happen often with the tech non-savvy, they somehow manage to move the file into some random directory somewhere. They're now waiting 10 minutes for the LLM to scan their entire system for MyTaxes(327).rar.zip, only for the "agent" to shit itself upon encountering some sort of permissions block, or for the unzip toolcall to fail, or myriad other reasons why this could fail. Now what? Do you think laymen like these have the patience to guide the stupid bot do to what they want via verbal instructions, when they can't even be bothered to double click a zip file which on any modern system in the last ~10 years will simply open the zip file?
People in tech severely underestimate laymen's computer acumen, and they SEVERELY underestimate people's willingness to put up with software, there is no universe in which they will patiently sit there while the LLM goes through the "thinking" process to operate their computers.
Hell, I work in a tech company and I am often dumbfounded (in a non-judgy way!) at how little people understand their systems or how any of it works despite spending countless hours on their laptops every single day. I don't even mean the nitty gritty technical details, just stuff like "Where did I put that file", "How do I open this mp4 you sent me?", "What do I do with this .zip file?".
