I wouldn't discount something simply because the underlying technology has been around for decades. People said the same thing about Slack being nothing more than IRC. Didn't stop people from talking about how it was the future of work, or whatever.

For that reason, and many others, we really shouldn't ignore the amount of innovation in software and web that is largely design-oriented rather than engineering-oriented. A lot of venture-funded darlings out there are built on decades old technology, the key difference mostly being the design decisions that went into the product.
