Look, you don't owe anybody anything, and that's fine. Just don't make promises you can't keep. If you're not going to have something done in 2 days, don't say it'll be done in 2 days. Just say "you'll get it when you get it" and that's an absolutely fine response. But promising something in hours or days and missing that deadline will lead reasonable people to take your claims with a huge grain of salt.
All I'm saying is you've made some very big claims, so now you might want to master the fine art of setting expectations or risk making people lose interest in your project when you finally release a compiler.
