Explanation
This comic satirizes the trend of people using elaborate philosophical or pseudointellectual justifications to avoid doing things they simply do not want to do -- in this case, going to work.
The character is lying on a couch, talking on the phone, and says: "Actually, it would be DANGEROUS for me to come in to work today, for religious reasons of which you are WELL AWARE." The emphasis on "dangerous" and "well aware" parodies the kind of aggressive confidence people use when invoking vague but unchallengeable excuses.
The caption below reveals the "religion" in question: "Ever since I accepted the Simulation Hypothesis, I've been trying to use fewer computational resources to lower my risk of getting switched off." The Simulation Hypothesis is the philosophical idea (associated with Nick Bostrom) that our reality might be a computer simulation. The character has twisted this into a religion and reasoned that if reality is a simulation, then using fewer computational resources (i.e., doing less, being lazy) makes you less likely to be noticed and shut down by whoever is running the simulation.
The humor works on multiple levels. First, it is a clever parody of how people can take any intellectual framework and contort it to justify laziness. Second, it satirizes the way the Simulation Hypothesis has become a kind of secular pseudo-religion in tech culture. Third, there is an ironic truth to the logic -- if we were in a simulation, doing nothing really might be the safest strategy -- which makes the excuse funnier because it is both absurd and internally consistent. The character has essentially found the perfect unfalsifiable excuse to never go to work.
