 Excel is a fantastic tool, and you still need to know it for data analysis. And I think as you get further along, that's why people start really not liking Excel, is they start using it at the beginning. It's great. But then they find all these different use cases, why it doesn't work. And everybody else in the business world, everyone else that they're working with, wants everything in Excel. And so since not everything is super native to Excel, you have to figure out little workarounds and little ways to get it into Excel, which gets super tiring and really frustrating. So Excel is kind of that one thing that does really well in a lot of areas, just as an Excel in every single area. And so you have all these specialty tools and all these different plugins that you have to do outside of Excel and then bring it back into Excel. And that's, I think, the part that makes people the most frustrated.
