Its funny you mention excel, I see vibe coding in the business sense right now being a gateway to replace all of the ad hoc uses of excel. We've basically leveled up the quality of the software you can build before buying a SaaS product or a hiring an in house engineer.
It was 2020 and they were using a format that was replaced in 2007.
It. says more about their issues than Excel. I doubt paper forms would have saved them. Maybe they'll run out of paper and just ignore new entries too.
The moment vibecoded excel has a bug that regular Excel doesn't and a user has to wait on you to re-vibecode it's over. They'll just use Excel while you're trying to get the llm to find and fix the bug.
