A lot of Web3 developers are inexperienced developers. That means they are fairly new to development. They should build something that works first before they get into blockchain development. Accept an internship, get a mentor, and work on a team that is actually building something useful ... in Web2. Then, after getting their feet wet and being successful at something, they can turn their attention to Web3 development. They don't get the basics right because they're thinking isn't basic. They have a first-day employee mindset with CEO aspirations. It doesn't work.
