What if we discover that the universe is just computer simulation

It would make no difference what so ever. Everyone would still go about their business, as they’ve always done - eating, sleeping, mating, and defending.

Besides, we already live in a simulation - this world is a material simulation of the eternal reality of the spiritual world.

The material simulation of reality created by God is so clever that we don’t even realize we live in a simulation. We think that our body and its culture is completely real.

It’s a very rare person in the material world who wakes up to the spiritual reality. In fact, very few people even want to wake up to reality, they want to stay in the material simulation, so they can continue to enjoy their senses. They are so firmly bound up in the material illusion of family, friends, nation, and love, that they can see no reality beyond it.

Nobody is as hard to wake up as the one who wants to remain asleep.

The sole mission of the human life-form is to break free from the illusion of bodily identification, and wake up to the reality of the soul, but in contemporary culture, ruled as it is by ungodly forces, a deliberate campaign is conducted to keep people from waking up to the eternal reality of Krishna.

The demons who rule the world want to keep people as mindless robots in a simulated reality defined by the body and its culture. In such a bodily oriented culture the main agenda is set by how much a person can consume.

Such demons were predicted by God in Bhagavad Gita, already 5000 years ago.

Krishna says:

Those who are demoniac do not know what is to be done and what is not to be done. Neither cleanliness nor proper behavior nor truth is found in them. (Bg 16.7)

They say that this world is unreal, with no foundation, no God in control. They say it is produced of sex desire and has no cause other than lust. (Bg. 16.8)

Following such conclusions, the demoniac, who are lost to themselves and who have no intelligence, engage in unbeneficial, horrible works meant to destroy the world. (Bg. 16.9)

Taking shelter of insatiable lust and absorbed in the conceit of pride and false prestige, the demoniac, thus illusioned, are always sworn to unclean work, attracted by the impermanent. (Bg. 16.10)

They believe that to gratify the senses is the prime necessity of human civilization. Thus until the end of life their anxiety is immeasurable. Bound by a network of hundreds of thousands of desires and absorbed in lust and anger, they secure money by illegal means for sense gratification. (Bg. 16.11-12)
