Yes, most hydraulic systems today have been replaced by electric power steering, which uses electronic sensors to determine how much assist to apply via an electric motor.
one small nit to pick
many modern electric power steering systems are still hydraulic by nature. It's sometimes the case that the electric motor is driving fluid to enact the resistance change. Many cars that use Bosch electronics/driving-aids still work this way, electro-hydraulic pumps in a feedback loop with pressure sensors/steering angle sensors/IMUs/vehicle dynamics sensors (speed/angle/yaw/etc).
That said, fluid-less electronic-exclusive systems now exist and are in common-use, so you're not wrong at all -- just pointing out that there are many ways to skin that cat.

No they aren't. I have a car with EPS (electronic power steering) and it isn't playing any tricks. It's just an electric motor. What you are talking about is EHPS (electro-hydraulic power steering). Stop mixing up your terminology.

are you sure? there's a lot of "normal" cars that are full EPAS. Like the Prius.
I know stuff like the MR2 is like that, but I'm guessing that's because the engine is in the wrong place to have normal power steering.
