They have computers and alarms, but it's up to the operator to give the

Seems to me that you could put weight sensors on all the outriggers. When
any outrigger weight drops below a certain threshold, an out-of-balance
alarm can be presented to the operator, and if the weight continues to
approach zero, the system can lock up, preventing the load from being
extended any further.

And a bad sensor could cause a worse condition. The human has to have
ultimate control, with the machine just providing warnings for the human
to validate.
