I think it depends on how tech savvy and willing the person is, it really is not complicated to use but some older people I know tend to shut down at the sight of something techy without even trying.

That is just my experience when I have tried to share different things with my grandparents etc, but I absolutely think it could an amazing asset - it would keep the mind and body more active and they can create things (always brilliant in my mind)

I'd say it is worth trying, even if you start by showing them some youtube videos to test the water first and see how they react to the idea.

Anyways hope this helps :)
