This is cool, but yet I’m continually unimpressed with how slow the actual experience of using a computer is. Some of the simple text-based UIs from the 80s respond in <50ms, but it takes 10+ seconds from opening the Facebook app on iOS 11 on a 6S+ before I can start typing into the post text area. We can load a gigabyte in 2 seconds, but how long does it take to complete an actual task? Basically, I think that we’re not solving the actual experience problems with computers or in mobile. UI lag has gotten noticeably worse in the past few years. Android was terrible at this when it first came out, but iOS 11 did something that causes the Home button to now skip a few beats before responding. Excel was reasonably fast, but then everyone moved to GSheets, and it’s back to being as slow as an original Pentium running Win95 doing the same calculations (I’d love to actually benchmark this — “normal” $600-ish PCs from every 5 years going back as far as I could running some spreadsheet responsiveness tests).

Computers are fast, but software is slow. Software gets slower faster than computers get faster. “What Andy giveth Bill taketh away” is still as true as ever. I’d love to see the industry move to focusing on responsiveness and e.g. timing on productivity tasks for power users (automate the tests) instead of thinner bezels and flatter UIs.
