I think you can do things you already know how to do without trial and errors but that you can not learn knew things or tasks without trial and errors.
That’s a reasonable position, though I’m not sure if it’s OP’s.
My own sense is that even for novel physical systems, the ‘how could we have foreseen these results’ question tends to get answered—the difference being it maybe gets answered a few decades later by a physicist instead of immediately by the engineering team.
