NoSQL DBs have real advantages - e.g. you have a huge production relational DB, you want to make schema changes - you have to take your app offline for hours.
No. You can migrate big production relational DBs with much less than hours of downtime; sometimes there's no downtime at all. Please, either qualify your statement, or stop speaking in such an absolute sense.
Would you mind expanding on how to minimize downtime when applying migrations to large DBs? It's clear the grandparent isn't familiar enough with the relevant techniques to realize their statement needed qualification, or could count as "nonsense", so they could probably benefit from the explanation.
If you're taking down a SQL DB to make schema changes then you're doing it wrong. Even resource-intensive changes can be done online by applying the changes in stages.
