• Hi guys, I’m going to start a company. It will be important. But it will also suck. It will be valuable. But will leave death and destruction in its wake. It will be transformational. But it will destroy society as we know it. So bottom line, please buy my company’s product. You can count on us! Thank you.

• I'm impressed with Claude Design. I see its disruption starting with smaller teams. As a founder I find myself turning to it more and more for the convenience of one-off design tasks. Sure, it's super slow, and one-shot quality is not quite there, and its image capabilities suck, but using it in between multi-tasking other things, it's helping me move faster. As @HarryStebbings says the "all-in-one" Claude interface has a huge psychological advantage as being the place people are already working. I don't think it's a great tool yet for a designer-designer (the speed / control dials are not ye…
