It sounds like the lecturer is speaking
Can you even do this? like the computer busy programs itself
I guess that lecturer's meaning might be "the computer busy itself with (writing) programs"
dictionary.cambridge gives this example of "busy"
I busied myself with tidying up my desk.
lexico gives this example of "busy"
‘she busied herself with her new home’
With the lecturer's usage, this example sentence could be rewritten as "she busied her new home herself"
Is this expression a clear and normal using of "busy"?
