The 'great filter' is a speculation on why we haven't detected any alien civilizations. A more reasonable explanation is that extraterrestrial civilizations are just much more rare than some people think. There are still gaps in the Drake Equation, one or more of them may be close to zero. We might just be the first and so far the only technological civilization in this galaxy, for instance.
Speculation (untestable hypothesis) is not a good foundation or support for a position.
