I am very confused with the phrase ' in the next seven years '. The full sentence is "Before discussing the type of technology that will be at play in the future, take a quick look at what might be expected in seven years and then in the more distant future."
In this case, does this mean that it will happen after 7 years? or within 7 years?
I am very confused with 'in' in this context. Then, a new sentence says 'There will be considerable change over the next five years.'
Does this mean that 'in' is interchangeable with 'over'?
