What is the reason you couldnt use your laptop on the beach to do work in 2019? Probably mainly that you are either working or enjoying nature, not both, and if you're working, then an office with reliable Internet, no wind or sun in your face, etc, is more suitable/efficient.

Put another way: if my twin and I are both working at competing firms doing the same job, but I do it via satellite phone while hiking the PCT and he does it from in front of a keyboard, there is no way he's not getting more done, even with AI. The bandwidth of voice/text to speech is a tiny fraction of visual.
