The machine and cabinet are only about half of sewing. It really is fabric origami with occasional thread staples.
Sewing is not mostly sewing — it’s primarily cutting, fitting, and pressing. And yes, pressing is absolutely necessary. Don’t be younger me who thought pressing everything was being persnickety and fussy. It is persnickety, the same way that the difference between a crepe and a pancake is persnickety attention to detail. Pressing a seam sets the thread (makes it part of the fabric of the garment) and that stabilizes the seam.
