Modern business is remote.
A guy in San Francisco can hire a team in Bhilwara, India which is 11.5 or 12.5 hours different depending on daylight savings. They don't really have to speak the same language. They can use pictures and long, verbal back and forth to work out the details. The team in India mostly speaks English but they miss a lot of the nuance and intent. But, they're cheaper than developers stateside because you can't see they are coding from a shared computer in a rooftop attic and charging you for both their time as one teaches the other how to code over a dialup connection.
Communication is instant / not-instant.
An outreach to a company's sales team will get you an instant reply and plenty of quick follow-up conversations. They'll want to jump on a call and solve your problem today.
An outreach to a hiring manager will get you no immediate response and possibly an email six weeks later asking if you want to set up a call as if no time has passed. You quickly look up the company to remember why you sent them an email at all. You set up the call to see what modern teams are like.
