When did thinking go out of fashion?

​I was recently in an airport when I was confronted by a very large advert extolling the virtue of ‘never being out of reach’, another highlighting how in-air connectivity meant you could ‘take the world with you’. Everywhere we are given the option to ‘connect’. Yet I remember the days when a long flight gave me the opportunity to just ‘think’! I would use that time to consider large tasks and strategic decisions, that I never had time to think about with the daily barrage of questions and issues to be resolved. Today it appears that ‘thinking’ has no value, only ‘doing’ is seen as productive. Unless we are seen to be constantly active and connected, the impression is, that we are not working. Yet without the thinking time it is so easy for the ‘doing’ time to be wasted or ineffective, as we are reduced to a trial and error form of learning. I wonder how much time Einstein spent ‘doing’ vs ‘thinking’? Bill Gates is also reported to have often replied to the call to come down to dinner, with ‘I’m thinking!’
 
What priority do you give to ‘thinking’ vs ‘doing’?
How happy are you with the current balance of ‘thinking’ vs ‘doing’?
What needs to change to make both as effective as possible?
