Isn't        slow?

(yes)

Single threaded?

Lots of things are the same.

Estimates

Technology changes.

The other skills don't.

Practice both.

• Language (different paradigm)
• Data Store
• UI Framework
• Testing Framework
• Command Line
• Editor

Challenge #1

• Problem Decomposition
• Code Reviews
• Pair Programming
• Conflict Resolution
• Effective Meetings 
• Hiring
• Teaching
• Estimation

Challenge #2

AND

Have fun!
