Randomly thinking about this the other day, still think it's crazy that #Java was this huge important #ProgrammingLanguage when I was first learning to program back in the 2000s, then #SunMicrosystems was bought by #Oracle in the 2010s when I was teaching for the certifications, and now in the 2020s it's become this depreciated legacy language. The success of the less-portable and less-learned copycat .Net and staying power of the older #Python shows there was clearly a market for Java to continue, but the large #corporation was so much more interested in filing lawsuits against people who were doing things with the language than actually developing it further with modern features, they actually managed to push it into obscurity.
And we can't forget that this was a MULTI-BILLION DOLLAR LOSS. BILLIONS OF DOLLARS had been spent to build up infrastructure to support the widespread use of this language across the industry, so when they dropped all support, and all of that became obsolete for no other reason.
