it is about the positives of the UK FOLK REVIVAL.
If Technology because of its cost excludes those who cannot afford it or those old people who find it stressful, then whilst technology has positives for some. example.. those who can afford it but who are immobile, it appears   at the same time because of its cost to exclude.
    so yes it has positives, but how positive?
I see technology in the uk folk revival as a positive but something that could still be improved upon,[ example the inabilty to sing choruses together]
That is a positive statement.
I am sure you are not happy with the idea that there are some who cannot afford it, that does not mean that technology within the ukfolk revival is entirely good or entirely bad, but it means it has good elements and it has one or two things that could be improved.
