hydroponics was being pratice since the time of ancient babylon and aztecs. this is not a new technology as you presume. the approach was being reintroduce because of the some believe that many will benefit from this type of farming. there are plenty of advantages that farmers would get in their favor. higher crop yield, less water required, little risk of weeds and parasites, no need for crop rotation, continual growth throughout the year. most of the nutrients needed by plants are present in soil, but soil are not clean either, isn't it? but same as hydroponics you will not take the nutrients from the plant in that form. it will be processed by the plants to become edible one. and i believe most of us already consumed hydroponically grown veggies, if you are vegetable salad enthusiast who order it from some food chains, chances are you already ingested the vegetables which was grown hydroponically. for some producers adopt the same technology of farming. with regards to cost, yes some system are really expensive but there are some modified type of system which are low cost but are efficient in producing veggies such as lettuce, tomatoes, etc. these system will be functional and productive as long as you know how to maintain it. lastly, hydroponics uses sterile approach. as you can see on the pictures. the workers are wearing protective gears so as to prevent introduction of organism on the hydroponics system. these approach will be helpful in the decreasing size of agricultural land because of the increasing size of population.
