This is one of those big picture posts. Here're the "hard problems" I'd really like to solve:

• Code Comprehension: How to understand a new codebase easily. If i wrote an oreilly book it would be called "Understanding Code"
• Code creation and maintenance: A lot of this is manual, repetitive, lossy and tedious. Programmers should use the tools (that they make for users) for their own use. And: less snapshot-based development, more fluid one.
• Applying AI techniques to code itself.
