I like TUIs, and I chose to build e.g. https://taskusanakirja.com/ as a TUI for a couple of reasons, some of which are in this article and some not. Cross platform compatibility was a big one since at the time I started building it I didn't actually have a Windows or Mac machine handy to test this out.

One thing I think which is overlooked is the raw feeling of speed a good TUI can give you. The lowest grade consumer laptop could probably download my little dictionary program and still get true search-on-keystroke performance, because there is virtually nothing slowing down that path, no animations, no nothing. Now most of that comes down to the data structures involved and making sure nothing ever has to go over a network, but I still appreciate the sheer simplicity of the approach.

It's also nice to know that I can probably recompile this same exact code 50 years from now and still get it to run exactly as intended, since GUI frameworks have waxed and wanted in popularity, but terminals truly don't seem to be going anywhere.
