Does cybertruck have a steering column
No, the Cybertruck does not have a physical steering column. According to the search results, the Cybertruck features a steer-by-wire system, which means that the steering wheel is not directly connected to the wheels. Instead, the system uses electronic signals to control the movement of the wheels. This allows for more precise control and improved maneuverability, especially in tight spaces.

So yes, if there is zero power to the steering system, you're toast. Presumably there is a dual redundant system to keep it powered, I'd guess it's fed both from the HV battery via a DC/DC converter and also from the low-voltage battery. It also likely has two independent motor coils. However, there are a significant number of potential common-cause failure points, most notably software errors - I'd be
amazed if they had diverse redundancy in the software for that system. I assume Tesla have followed industry standards for functional safety, but it's really hard to know for sure since none of that is ever public record before an incident.
Steer-by-wire is an interesting example of "let's take a relatively simple system, and make it vastly more fragile by making it fully electronic." Sure you get some benefits in terms of flexible control and the crash safety of not having a steering column, but the tradeoffs are many more "electronic and software" failure modes. A simple example is back-up cameras. Yeah they help with a severe corner case - but you would be amazed at the complexity that goes into making sure that image is reliable compared to a simple piece of silvered glass.
