Intel has already tried this (CPU+GPU+NPU) in partnership with Asus [1]. Big announcement at CES back in January. Not seeing much traction. Let's see how this one is received.
You just described the absolute nightmare scenario for the newly minted trillion-dollar companies whose only hope is for enterprises and SMB to move all their business processes to the cloud, with employees competing at token maxxing.
If people figure out how to run agents on-prem (already becoming feasible for both agentic tasks and coding on consumer hardware like Mac Studio 128GB+ or DGX Spark with some models) these companies will be in deep trouble.
Looking at the comments here, it appears people are trying to do too much, too soon, which inevitably backfires. The key is to put OC in a sandbox (don't give access to your real accounts, it must have ints own separate non-admin accounts for everything only "invite" with limited access as you would a contractor) and generally treat it as a new employee during a trial period. You'll be surprised by how effective it can be if you pace yourself.
As for "you can easily do X,Y,Z with a cron job" we tech people often underestimate what hiding the complexity could do for UX.
"For a Linux user, you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem." -- top comment on "Show HN, Dropbox (2007)
No recurring expense, just the hardware upfront cost. My next step is run the models locally as well. I used to work at FAANG (incl. compliance) and I would never use a cloud-based assistant of any kind.
Operations: mostly tasks and reminders, I often think of something while on the road and send a voice message (like I would to a real PA). I use Kokoro-based TTS for local text-to-speech. Anything from "remind me to discuss X with so-and-so tomorrow" to "I have a multiple PoC projects w/ large entities starting next week - think about how I can best handle that" to "brainstorm how can I maximize upfront revenue with them", etc
Sales: using Google/gemini web search API and it's best run off-peak due to rate limits 503 Service Unavailable (everyone is overbooked when it comes to AI) to see what's happening in the space, any new developments involving companies I care about - and send me a daily digest with an overview and conversation topics.
