Is the mainframe still necessary? Well, let's put it this way: If all the world's mainframes shut down, we'd be facing a zombie apocalypse. That's a bit hyperbolic but the underlying point stands: Without mainframes, banks couldn't process financial transactions at ATMs or online, retailers' ecommerce platforms would go dark, and healthcare systems would be unable to access patient records or other vital information. Mainframes are still a vital part of the modern enterprise. If they no longer existed, businesses would lose access to years of records and entire computing systems would crash.
