Scala as the new Java?

Question

I just started exploring Scala in my free time.

I have to say that so far I\'m very impressed. Scala sits on top of the JVM, seamlessly integrates with existing Java co

The two, by which I mean four, biggest downsides I'm seeing are:

• Many working as developers in the professional community aren't trained and are unwilling to learn how to use a functional language, they won't even give it a go so they can understand why it's a better approach. This means you'll always be fighting an uphill battle getting adoption until it's mandated at the corporate level.

• RDBMS integration is still a bit spotty. Plenty of solutions, but nothing that really sticks out as becoming a standard. For me though, this might be an advantage rather than a disadvantage. JPA2 is a mess and causes more issues than problems it solves. Hibernate criteria queries aren't much better.

• IDE support is still lagging, but mostly in the area of debugging at this point. Code inspection is doing pretty good (at least in IntelliJ).

• You'll never want to write another line of Java again! Likely you'll want to punch a wall or break something when forced back into the awkward syntax of Java.
