I don't see anyone creating anything with an 8-track or VHS tape except as a novelty because it would be painfully slow and the quality not up to par compared with what we have now. It's only useful if he's creating stuff and earning money/fame/fulfillment or whatever rocks his boat. But as 'investment' for some future date when he decides to use them he might be better off investing the money pending that future date which brings us back to square one.

You're describing obsolete formats. Some stuff that was first created during the 8-track era is still desirable and available in other formats.
Besides, I took his comment to mean that he's buying the equipment to develop new and marketable skills.
