The term godspeed, used in such popular culture situations as The Simpson’s, “Godspeed, little doodle,” or Spider-man, “Godspeed, Spider-man,” has nothing to do with wishing for god-like-speed.

According to my best friend,

The Term “God Speed” originated in the Old Testament part of the Bible, in the
book of Genesis 24:12 in the King James Version, when Abraham’s servant,
Eliezer, prayed for success when he was sent to find a wife for Abraham’s son
Isaac. The original Hebrew word for “speed” in this verse is הַקְרֵה, pronounced
“Haq-rei” and it means “to encounter” or “to meet” in the causative form: “And
he said O LORD God of my master Abraham, I pray thee, send me good speed this
day, and shew kindness unto my master Abraham.” (Genesis 24:12 KJV).

Furthermore, it means:

1) An expression of good will when addressing someone, typically someone about
to go on a journey or a daring endeavor.
2) A Christian substitute to the otherwise sacrilegious “good luck”, which implies that anything can be random and out of the hands of God. Used to express concern and prayer for someone.

I think this is all very misleading…
