People use low-compute models in their day to day jobs. They're not exposed to how good the very-high-compute runs are doing at the moment.
Thermodynamics is the law of laws, unless they invent some kind of ultra-efficient, almost magical computers to run these systems, it's simply not economical yet.
The reasons could be that it's new (they did say they plan to release eventually but not soon), or that it's too heavily scaffolded for the task and not sufficiently general.
