Definitely NOT. Image stabilization is only for higher end action camera. I've seen some digital stabilization on cheap cameras, but they're pretty much useless.
In fact, if I'm not wrong, GoPro didn't even have image stabilization until Hero 5.
A lot of people on YouTube who did motovlog for example, had to buy a separate software to add image stabilization while editing the video.
Other people decided to use Gopro Karma Gimbal to stabilize the video.
The best Image stabilization is without a doubt, Sony's balanced optical stabilization (AS300 and X3000)
However, GoPro has done a good job this time and Hero 7's digital stabilization is almost as good as Sony's balanced optical stabilization.
