One-man show here - I own a dozen small e-commerce brands. I'll assume you're just taking away AI, but not the tools I've built with AI.
I've got all kinds of useful tools that do helpful things, like check to make sure Amazon hasn't lost a bunch of my inventory or suddenly deindexed my product from search. These sorts of things happen without warning from time to time and are trivially fixable if you catch them, but you have to be constantly monitoring 10 different things to catch anything that could go wrong in a timely fashion.
I've similarly got an inventory/cashflow management system that's deterministic that would be fine, but some of my other tools, like one that scrapes my Alibaba/WeChat/Whatsapp/Gmail supplier convos to keep my order status board updated, is finicky. I wouldn't be able to repair that once it broke.
For some tasks, I'd have to go back to freelancers. At this point, when I take over a new brand and want to refresh images or want to A/B test new ones with an existing brand, I can do that entirely with image gen. No AI would just send me back to Upwork.
For other tasks, I'd just have to do them myself. Right now when I acquire a brand, I have a Claude skill that runs through all of the Amazon search and ads reports to find the key search terms, analyzes the text of the listing and proposes updates to make sure we're hitting the ones that matter. I used to do that myself, but it takes somewhere between 2-10 hours depending how many products we're talking about.
The biggest loss would be the inability to expand. I started out just buying Amazon-only brands because Amazon provides a crazy amount of infrastructure that enables me to run a lot of them by myself. My most recent acquisition came with a Shopify site that had minimal sales plus a Meta ad account the guy who sold me the brand had done a little experimentation with. A year ago, I would've just discarded those, since my time is the biggest bottleneck. It takes a lot of time to run your own site and Meta ads, so it makes more sense for me not to bother and instead just make more Amazon-only acquisitions.
But now I'm having a great time really pushing Claude and ChatGPT to do most of the work. I redesigned the site more or less by just having ChatGPT do research on competitors and best practices, then having Claude run with that. That took maybe eight total hours of work.
I'm spinning up an enormous amount of creative to test on Meta, and I had ChatGPT research and spec all of the kinds of landing pages that are worth trying. Claude implemented them and set up the ads using Meta's ads APIs. I got all of that done yesterday.
So yeah, basically if I couldn't use AI any more, I'd get back to the original thesis of my business, which is buying small brands at reasonable prices and operating them as leanly as possible. It still works, but it'd be a lot less fun and profitable.
Off topic, but where do you find these brands to buy?
