would think that this machine is adequate for an architect, engineer, or scientist? - no one but you - I think.
Architects and engineers use CAD software and need large screens. Scientists crunch numbers and use modeling software that requires a faster processor, more RAM and powerful graphics.
A Surface Pro could be a supplemental computer for architects, engineers, or scientists when they are away from their desk (presentations, note taking, meetings, remote desktop) but it is not for heavy lifting.
That's like asking a truck driver if he could "make do" with a mini Cooper.
