This isn't true. There are sibling comments here that mention the same, however, to add my own point here: I'm involved in a complex hardware plus software project which involves designing and doing a board bring-up for an Arm SoC Linux-based device. We need to visit the office only once in two to three weeks. For the board bring-up when we do not have the provision to provide the hardware to our software engineer yet, we have someone in the office connect the UART lines to it and have the typical VPN+SSH set up to perform the board bring-up for it. Generally speaking, the engineers that are required for the labs would be electrical engineers and mechanical engineers. Also, even for these physical-based engineering disciplines, a lot of design is highly computer based thanks to great CAD, simulation, and future-looking generative design software from the likes of Autodesk, Ansys, etc. That being said, I personally feel that being in person really can help in the epiphany process for hardware-based projects.
