The International PHP Conference has posted the video they recorded at their 2010 event of Pierre Joye and Johann-Peter Hartmann's keynote presentation "PHP: Yesterday's Scala and the Cobol of Tomorrow".
PHP came a long way, and we are no longer the cool new kid on the block. On the other hand side we are still far away from being the new cobol, and there is a lot of great stuff going on inside php and the php community. What happened to PHP the last few years, what is happening right now and what will be the next 5 years? Is PHP ready for nowadays trends? Does it fit for Social Web, NoSQL and HTML 5? Should You better be learning Scala right now?
The video runs about 45 minutes and compares some of the features Scala offers, a brief history of PHP, some of the trends of current development and where PHP needs to go in the future to keep up with trends.
