As a beginning amateur woodworker with an extensive Youtube education, but now being overseen directly by an actual professional woodworker, and without intending any snark or malice, let me just respond to that: "hahahahahahahahaha".
Watch someone hand-cut a dovetail (heck, watch 10 different people hand-cut them), then get a chisel and a coping saw and a marking gauge and try it yourself. It is not easy, even if you (as I did, to little effect) condense all the video tutorials you watch and the chapter in the Tage Fried book into written step-by-step plans.
You can absolutely do it! I'll eventually be able to do it semi-competently, I think. But I doubt you'll get there without learning to respect the challenge at least as much as you respect the work that went into getting you to a comparable level of coding aptitude.
