Steins;Gate: Evidence for a Simulated Reality?

In Steins;Gate, the world seems to have an automatic error correction mechanism, erasing events and characters that deviate from a predetermined path. Protagonist Okabe Rintarou repeatedly tries to alter the past to save his friends, only to face failure. This resembles a running simulation correcting 'errors'. Okabe's eventual disappearance, restoring the world to 'normal', suggests his actions were anomalies, purged by the system. This raises the question: are we living in a similar simulated reality?
