Show HN: I've built a C# IDE, Runtime, and AppStore inside Excel
Jokes aside, this is an amazing achievement, the more so for being realized by a single person working away patiently for years - truly inspiring. And it brought out a wave of nostalgia for a former life where I made a living building bespoke tools in the (pre-VBA) Excel macro language. All that and solid business sense too! I hope companies shower Antonio with money, and that Microsoft either leaves him alone or rewards him with gold and the autonomy to lead technical product development for the long term. It's rare to see such a singular combination of vision and execution, doubly so in a very mature product space belonging to a global megacorporation.
