Lean is the result of over twelve years of continuous development. We designed and built every layer from scratch: the trusted kernel, the compiler, the language server, the IDE, the proof automation. The team is 20 people. The community independently chose Lean: mathematicians, AI researchers, and enterprise engineers, all building on the same platform.

Adrian Kingsley-Hughes/ZDNET One important note: power banks don't like being baked in the sun. Overheating can damage the battery and slow down recharging. It's far better to attach the power bank to the back of a backpack, where it gets plenty of airflow, than to leave it roasting on a car dashboard. I've seen reports of solar panels peeling off, which is likely due to excessive heat exposure (the manual does warn against this).
