I'll answer that I think this parliamentary committee is taking steps in that direction by drawing on such a wide group of interprofessional and interdisciplinary experts.
Another thing that's important is for there to be opportunities for employees of companies that have the largest datasets which might be used to be compelled to provide evidence on how they're using these technologies as well, in order to inform legislative approaches. They could be company employees who come out and are whistle-blowers, who are then able to report to these committees in some sort of way.
Drawing on what people know within industry, to equalize and create a proper symmetry between what you know as legislators and what companies know internally, is probably very important.
