AFAICT there have only been two programming languages that people rely on today that were created after the year 2000: Go and Rust. Both were sponsored by large organizations which had clear goals that drove the design and development. All other modern languages are not going anywhere. The days of Python and Ruby and Perl and PHP being personal projects that people created, that grew into widespread languages that other people use seriously, are over. (Zig feels like it's a potential counterexample, but it's already been 10 years; for every other language mentioned above, after 10 years they were clearly well along their adoption curve.)
