Hammers and screwdrivers are - I think - pretty mature tools. Still lots of people do not care for DIY and prefer to buy premade or pay someone else to take care of custom solutions.
Hammers and screwdrivers still require quite a bit of thought and planning. IMO, the tools of the "real computer revolution" won't be done until they're at least as effortless as the Star Trek holodeck ("computer, give me a table here, made out of metal").
