Just tell them to do microchip programming, like on an Arduino. Though, the idea of 'it works faster' in comparision of todays software is not really valid, as the expectations and requirements of software have gone up since 2000. Of course Firefox 2.x was fast and not memory hungry! It didnt have to: - support x64 - support new web tech like WebGL, WebRTC, Crypto API, all CSS options, the latest JavaScript specs - update rendering engine for CSS3 - support retina/hiDPI - handle webpages that are big in size + have loads of javascript libraries + multiple advertisement parties - update to a modern UI - implement new cryptos for HTTPS - ship with lots of rejected certificates - still support old systems - do all this in a secure way
