I would strongly suggest not updating at this point.
I'm a 35-year computer user and have been using macOS as a daily driver for the last 5, and my career experience would put me in the top 0.1% of the tech industry -- and this particular change has ME frustrated and has diminished my productivity significantly.
This is not me being "change-resistant"; it's literally erased a function that EVERY desktop interface (Windows, Linux[both gnome and KDE] and all prior versions of MacOS in the last 5 years have) -- the ability to click on a "start|launchpad|etc" button and start typing the name of an application, and have that application come up within 3 characters.
This is a universally-accepted UI feature that everyone who's used a computer within the last 15 years has come to know, and this force to spotlight (which literally nobody finds useful) has eliminated it.
