This PROVES you WRONG !

"We have received a report of two occurrences of engine thrust rollback
(reduction) during takeoff on Boeing Model 777-300ER series airplanes powered
by GE Model GE90-115B engines.

Investigation indicates that these events are the results of a software
algorithm in the FADEC that was introduced in software version A.0.4.5
(GE90-100 Service Bulletin 730021). "

I thought the BA 777 had Rolls-Royce engines.

It does. But both the relevant RR and GE engines use FADEC which requires software.
Neither engine has a mechanical throttle. It's controlled ENTIRELY by electronics.

My comment doesn't relate to who made the rotating machinery, but the opportunity
for a software induced failure.
