Not quite, a linux system of ~2010 has several advances over a Unix system/V from the late 1970's it's a late 1960s muscle car compared to the Model A of PDP-11. Same basic technology under the hood, but refined and much better understood. Most of the "advanced" programming environments look very nice but fail to meet the needs of real world usage; where you have to talk to other systems and get dirty doing it.
