Not to mention that they get mandated regular reviews of their ability to fly manually. And even with that, there's still a reason why "children of the magenta line" (i.e. pilots who passively follow automated systems into danger and/or have seriously degraded stick-and-rudder skills) has become a term.
Taking off, flying, and landing are all absolutely required in the normal operation of a plane. If your plane is not engineered in such a way that landing is normal, it won't last long
On top of that I'm sorry but you seem to have skimmed over both the article and what I said in favour of clutching pearls at some nebulous entity apparently claiming that "automation should be ripped out" when what is actually being explained to you is that without actual, manual, hands-on, current experience the "human in the loop" loses the ability to properly control or take over from an automated system - and worse, the ability to even understand when it is doing something nonsensical and/or dangerous.
As an aside, I assume that by "radar systems" you are referring to radio navigation aids. Like I've already mentioned (though in fairness not everyone knows what a non-precision approach means), pilots of airliners are still trained to fly without them, are expected to know how to fly without them, and shockingly enough DO fly without them in the real world where equipment fails or cannot even be installed at all. I know most of the software that people write here is insulated by several layers of abstraction from the hardware, but surely we haven't already lost the understanding that automated systems are not in fact magic - that they depend on real world hardware with real world physical constraints?
An abnormal landing would be something like trying to land with a broken elevator surface.
Landing after a merely unstable approach, too many significant changes too close to landing, increases risk.
Landing too fast may result in overrunning the end of the runway, pilot induced oscillation, or loss of control. Energy being proportional to the square of velocity means the margin doesn’t have to be huge to pose significant danger. Landing too slow risks an aerodynamic stall or worse a spin, which at low altitude is nearly certain to be fatal.
Landing safely with a crosswind requires technique changes. Too much crosswind or “running out of rudder” is extremely dangerous.
Landing after accumulating airframe icing is triply bad because the ice reduces the control surfaces’ aerodynamic effectiveness, makes the airplane heavier, and requires a faster landing.

A more recent example is the Boeing 737-Max where there was a focus on automating trim control. In that case, the automation made the system more complex, to the detriment of a pilot understanding and reacting to an abnormal operation.
We should also be careful that we don't create a false dichotomy between "all automated or no automation", or an expectation that more automation is always better. The goal should be the right balance that increases reliability/safety.
Any equipment on the aircraft can and will fail. Becoming dependent on autoland — not a worry on most general aviation aircraft — is terrible risk management. Every pilot must maintain hand flying skills. Automation is nice and reduces workload, but the pilot must actively manage it.
