If a computer could truly model life then you could have some ridiculous Star Trek TNG holodeck episode as reality! I seem to remember such an episode.
Never mind “life”...just our surroundings are complex beyond current “models”...the holodeck would be an easier task. And we’re not even there yet. Whatever may be attainable in the future is certainly thrown back for decades by the current waste of resources on the Western PC clusterf**k.
