I would get one.

First, I generally would wait to see how the Apple Silicon laptops do in the real world. I'm sure they will eventually be very great, but I wouldn't buy the first generation just the same as I would not immediately upgrade to a new version of OSX/macOS.

Let the bugs get worked out, let other vendors pick up their own support for it, then take a look at if it's worth investing in.

Second, even if Apple drops all support tomorrow for their Intel line, you still have a working setup that can take you through at least 3+ years of use before needing an upgrade, including software (Brew, MacPorts). Your DAW won't immediately stop working. SSH won't stop working. There are still companies that let you download older versions of their software (Cubase, for instance). If another big Heartbleed-like issue is found, get the update from HomeBrew and set your PATH to use those binaries instead of the default ones.

Lastly, your Intel Mac is still a computer. You can install Linux or Windows and get extra use out of it.
