It's really too bad you didn't feel the need to google that question
Because hit one would have been a great answer! "15 Film Cameras you can still buy brand new".
Now, this is the top google hit (Because the Exchange network is awesome for searching and finding answers as a Q&A site)
Additionally, cameras don't really take "slides or negatives", film cameras expose film, and then a lab converts the exposed film to slides, negatives, or digital (Often throwing away the negatives today)
And lastly film is making a comeback! At least for now. A generation has never really seen analog photography and are apparently fascinated with the process of it.
And we really shouldn't approach problems with the "kids these days" trope. Today's kids have inherited an unprecedentedly peaceful world, with access to incomprehensible data and unceasing social interactions. Maybe the world has forgotten how much the world has changed since the internet came out, but I haven't forgotten how amazed I would have been in the late 90's if Yahoo, Lycos, AOL, or even Google would have returned search results as relevant as these
(And for the Exchange members who are clamoring for how off topic this is, I really wanted to leave a long comment or a thread in Meta but neither is possible)
