This is somewhat off-topic but I might as well ask this here: who are respected technical people who support Bitcoin Cash?
Lightning Network isn’t even required, just simple unidirectional payment channels would allow them to amortize the transaction fees over many transactions, and be instantly confirmed.
The only tricky bit is the sender knowing when it can go off-chain. With BitPay soon requiring Payment Protocol that becomes easier [1]
Agreed though, payment channels have been around a long time.
