Here's the current state of the tech industry: A week or so ago I went for a big group meal and at the end they brought the card reader machine for us to pay and it had an option for us to go through an itemised bill, check some options, and pay for just those options (plus an equivalent fraction of the service charge). It was amazing! This genuinely saved us about half an hour of talking at cross-purposes and poking numbers into our own phone calculators and hoping nobody did the sums wrong and accidentally stole someone else's tip. I genuinely would consider going back there for future group meals despite the fact that I'd finished my food before Alec's arrived and he'd finished his before Darren's came, so thoroughly do I dislike the traditional bill-splitting process. And yet in terms of technology, it was nothing but a low-end smartphone running an app built entirely from OS-standard UI components. No AI, no invasion of privacy, no adverts, and I have to assume no VC funding or elaborate toolchain. Just a good idea implemented well, and genuinely we all went away commenting about how clever and useful it was. And I don't remember the previous time I experienced that. We know what people want. They want you to use the massive technological advances we've already made to build useful things that work. But apparently there's no money in that 🤷
