That's what scheduled meetings and Slack is for. I have scheduled meetings with the PM to discuss business requirements for upcoming features once every couple of weeks on average, and sometimes she pings me to ask questions outside of it or have an impromptu Slack call with screen sharing. It's not worth me driving an hour and a half to the office (and her flying from many states away) just so we can discuss these things in person. And the product is coming along very well. We just had a successful demo that impressed a lot of people and secured another year of funding. And this is the third major product I've worked on entirely remote, all have done very well. That's not including the video games I developed along with artists that I never met in person that also did well back in the day, where we only communicated with text via AOL Instant Messenger and sending files to each other via email.
