If you could get biology, but:

* taking less than 18 years to produce a new chip

* able to task-switch instantly (being a doctor one minute and being a lawyer the next, scaling up/down instantly based on current workload)

* having millions of identical clones that people intuitively understand how to work with

* with no need for toilet breaks, sleep, family emergencies, holidays, weekends and all that

It would be pretty damn useful.
