I don’t want to go ad personam on the blog author - but checking his socials he is not really experienced person.

I don’t think we have anything to discuss here. He seems just to want to do cool stuff and his drop of databases seems to be because he just doesn’t know a lot of stuff there is to know.

I applaud attempt and might be that his needs will be covered by what he is doing.

But for everyone else yes, pick boring technology if you want to do startup because technology shouldn’t be hard or something you worry about if you are making web applications.
