An excellent chef may know that midwestern wheat makes tougher bread than southern wheat, and that White Lily flower is a great brand for softer wheat with less proteins. But that's useless knowledge--and added complexity--for a total newbie who's never thought about what "rising dough" means.
One of my friends got into programming recently by building netlify-hosted react websites. Yes, his need to learn JSX and the strange capitalization of reactifiedHtmlAttributes is additional mental overhead, but because some onramps have gone away entirely, he won't have to worry about FTPing files up to a server, or Linux file permissions, or configuring Nginx, until he's established.
So whether it's cooking or programming, the "on ramps" have definitely changed, but it's never been easier for anyone to get started building high-quality products.
