To the OP: Your inquiry is similar to some others, and I'll offer the following...
I often hear about people wanting to "upgrade" to a DSLR (or whatever label is on an advanced camera). This step is about getting into a "system".
The base camera and kit lens is like buying a shiny new red toolbox that has some starter screwdrivers. A Swiss-Army knife is also a nice tool option. And the knife has a lot more features in it at the beginning. But the toolbox can hold a lot more things. Over the years, it will serve in many more situations than the Swiss-Army knife because of the additional tools that have been added. But if you don't add the tools, then the toolbox is bulky and ends up doing less than the Swiss-Army knife.
Describing a DSLR as an upgrade is like describing a car as an upgrade over a motorcycle. The "upgrade" isn't right for everyone or every situation.
The point is, a system camera is a great foundation for lots of photography options. But only if you're going to spend more (and possibly a LOT more) than the initial purchase. If you don't "grow into the system", then you might have been better off with an advanced point-and-shoot or even a smartphone camera. You certainly could have spent less money. So if you're ready to spend money (fortunately, can be spread over years), then join in the fun.
