is there any hope for someone to become a professional in the field without an electronic/computer engineering degree? I'd love to do stuff that I can actually hold in my hand (did some reverse engineering for a usb sound card and it felt rewarding cause I could quite literally hear the success), but I only have a computer science adjacent degree (BBa in Business Information Technology).

Given how many idiotic ideas are ‘patched’ or worked around in software, it’s probably pretty easy. Especially in the world of modern GPUs when only a handful of people at the factory are able to write drivers for it.

Hardware vendors lost the plot in the Winmodem era.
