Is linux hard?

OFC not, linux is very simple.
The complexity of linux is just a misconception, linux was complicated once upon a time and people are used to it.
This is the same as Chinese goods, they used to be of very poor quality in 90-10 - but today China produces a huge amount of high-quality goods.
If you are not sure if you want to switch to linux, try to install it as a virtual system - ubuntu and other distros can be downloaded from the Microsoft Store as regular apps.
