Why did the computer crash?

Because it had a bad driver.

With the advancements we've seen in technology over the past 20 or so years, how long will it be before we replace ourselves with artificial intelligence?

I think one of the most amazing things about being a developer is seeing the abstractions that have come about over time. From having to program in machine code and assembly, to now with languages like Java, where a lot of the boilerplate code is effectively abstracted out by frameworks.

In a way, it's a bit unfair on those in other fields that we get paid so well for doing something we love.
