My two cents,

I think the introduction of Gutenberg was needed. The average user needs a default page builder and post builder to design pages and post

However, since people are not adopting it as their primary builder, that’s still OK, but I would just leave it remain and let the market make add-ons for it.

Moreover, if I was automatic, I would use those billions of dollars to hire an independent company to design and create a new page builder for WordPress and compete in the market. I would like to see a page builder very similar to the Wixs editor or Shopify.

You have all the money, you have the market share, you have the full advantage, you can use that as leverage to introduce a new page builder and also maybe even have it automatically installed a new install.

I created a video on this and it seems to age well
