There is a lot of talk about adoption, yet what I miss, is any talk regarding technological development...

"The last block update occurred 35 minutes ago". <-- this is just from a random transaction I did today, and still pending whilst writing this.
Quite likely, no merchant or customer is fond of waiting for more than half an hour, when buying let's say for instance a pack of bubble gum of whatever other goods with their AUR's...

If adoption is being targeted before resolving and countering technological issues as above, I highly doubt any true success potential irl...
