Cost will continue to be a factor for many years. A panel of switches may cost $25, While an integrated LCD touchscreen networked back to a control unit may cost factors more. Construction being the low-margin business it often is, I would be surprised if too many LCD panels and voice activation is common in the near future. What I think is more likely are smarter motion/heat sensors combined with a scheduling system. During different times, certain banks of lights will turn on and off depending on the detection of people there. For conference rooms that may still need manual control lights for presentations, switches are fine because there's only one or two of them. No brainer.
