Good luck to them, but without an equivalent to Microsoft Access it's not really a replacement for Microsoft Office for many power users. (Yes, I'm aware that Access has some weaknesses as a database but for quick-and-dirty custom applications it's still the easiest platform out there.)
In 25 years I have never seen anyone use Microsoft Access in earnest. For the overwhelming majority of users I do not think this is an issue. The last time I used it was when studying for CLAiT Plus.
We used it at Altitude Software, as one of the possible database backends for our platform, there were indee enough customers that it was a requirement to also support it on our ODBC configuration.
During the MS-DOS => Windows transitions, some folks moved from doing xBase development into VB, or Access, instead of CA Objects or FoxPro.
... Wait, people are still using MS Access?! I didn't even realise that there was still a current version.

So I'm a big LLM sceptic. Seriously, you can check. But if there is one thing that LLMs _are_ quite good at, it is the sort of quick and (very) dirty custom CRUD apps traditionally produced with Access.
