I would say relational databases are far more scalable than NoSQL database

That is a false statement.

NoSQL databases can afford horizontal scaling whereas relational databases cannot. The main benefit of NoSQL databases is better scalability! Queries in NoSQL databases are ridiculously fast too.

Also, relational databases are far more resistant to change down the road than NoSQL databases.

The question is whether most apps actually need the added scalability with today's computing power considered; not whether there is a chance a relational database is more scalable than a NoSQL database.
