In this chapter, we've seen how we can take two relatively complex problems – cross-platform development and machine learning – and, leveraging some easily accessible services, create an application that, until a few years ago, would have taken teams of specialists years to write.
Of course, the application has taken teams of specialists years to write – it's just that you now have access to the produce of their labor.
Cross-platform development is something that many companies have tried to get right: with Microsoft adopting Xamarin first into the company (by buying it) and now appearing in the code base (the 2019 build announced that, in 2020, .NET would combine Mono, .NET Core, and .NET Framework into a single .NET – at the time of writing, this is simply known as .NET 5).
Machine learning is attracting billions of dollars of research...
