Elementary, my Dear Tech-Folk...
Given the tendency for companies to chase cost-reduction, I'm certain this "appealing future" will take place. Having said that And now I think about it, most major IT Services companies 'flow' their teams together in an ad-hoc manner that closely resembles Crowd-Sourcing anyway...
...and when the A-team finishes up, it's always left to some overworked bugger on the coal face (who is already booking 120% of their time) to pick up the pieces.
The downside (did I mention an upside? No? Ah, well that because there probably isn't one) in the IT Services world is that it always makes any change horribly expensive, as flexible teams need to carry their fully-loaded costs with them, wherever they go.
Wait a minute, isn't that how Hollywood works? Eureka!
