I'm looking forward to this to hear everyone's thoughts!

I currently disagree completely with the thought that Page Builders are the future. You're learning a system that isn't transferable to any aspect of building sites. You're generating bad code, slowing your website down, as well putting your business in the hands of someone else's business (see recent Astra snafu for example).

I feel like as developers we think that being able to do 'everything' is what's important.

No, what's important is the website achieves its goal. You can accomplish all of this without a page builder, just using Gutenberg and a good theme.

When full site editing comes soon, then there's literally no good reason to use a builder.
