True sign of the arrogant software engineer, believing they can single-handedly recreate an entire company just because they went to school in one subject for 4 years.
The only difference with engineers is they can believe at least in theory they could create the backbone of some services, so they could have a shoddy mvp made in a few days which they assume just needs a "little" work to top it off, whereas others can't start without tech help, but massively underestimate how much tech work is required for their ideas.
If you dont believe me, hang around a startup space and see how people talk about trying to find technical cofounders
