"If things go as planned, this may become a paid, ad-free, zero-tracking search engine."
In 1998 when Google's founders announced their search engine they claimed it would be less commercial, more academic, more transparent and they would avoid the influence of advertising. Did things "go as planned." Not even close. What is the lesson here.
Meanwhile, every search submitted during the "beta" period is subject to none of those limitations.
"So, if I am not satisfied with Brave's result, Google's result is on the same page, or just one click away."
Brave is not the first to do that. Check out Gigablast, for example. If I am not mistaken, they also claim to use an "independent index". At least, they provide the source to a crawler and server.^1 That is what people should be excited about. Not Gigablast per se but the idea of an open source search engine that anyone can run. searx is another project worth looking at.^2
How many ways are results promoted and demoted; what are the factors used. Are these search engines that comenters are recommending in this thread transparent. (Making promises on a blog is not "transparency" IMO.) Where is the source code. What are the various server settings that alternatives like Google, DDG, Brave, Startpage, etc. never provide to users. This stuff should matter, yet the discussion of search engines always seems to devolve into personal usage anecdotes and "search shortcuts". Every user has different needs and preferences.
There are many knobs in web search that advertising-supporting tech companies providing "search engine" websites will never let users twiddle. The source code for those servers is not public.
