I know he is talking about non-tech... The portfolio was an example where you can show your tech skills remotely.

As you said, the effort is to get industry and candidates under one roof. It would be easier if you could do it remotely, thereby decreasing the costs for all participants.

Showing your tech portfolio is basically zero cost - you just send them your link. Showing you're a good cook is not.

I still think the idea is good, but that makes it a tough business case. More a possible recruiting strategy for mid to high paying jobs in my opinion.
