There is not. PDF is more ingrained into our tech then ever before. Something like a a quarter or a third of the web is pdfs, it is the default archival format, and the only remotely plausible competitor for the core function of PDF (it more or less looks the same to me as it does to you and you for sure have the software to open it one way or another) is maybe HTML/CSS. There are competitors for the 8,000 other uses of PDFs but only one at a time.
