Don't count shed inventors/creators as not being able to make the world a better place.

It didn't take computers and large engineering teams to make the first successful air plane.

 

Just quite a few people who failed and died trying.

 

The most immaculate conception took place in a tool shed.
Most are now just being used as grow houses.
Its really a metaphor for life: Give a man a tool shed and he will build a plane...then he will grow weed and settle for cheap thrills.
