Most programs should be written in GCd languages, but not this.

Except in a few cases, GCs introduce small stop-the-world pauses. Even at 15ms pauses, it'd still be very noticeable.

Might want to read up on Ponylang. GC'd FOSS language without the stop-the-world pauses, demonstrating that it's possible. Should also be pointed out, that there are a number of proprietary solutions that claim GC with no pauses. Unfortunately, if coming from more common C-family languages, Ponylang may require more to get used to the actor model and different syntax.

There are GC algorithms that don’t require stopping the world.
