Tesla said this in 1926, that is 95 years ago, he said we would have what we have right now minus a few things we may not have right now. But we could have had them a lot sooner. But they stole his work from him. So, cell phones, computers, Internet, cameras, wireless technology, etc, were delayed many decades and also slowly rolled-out in increments. Most of the time, what the general public gets is 50-year-old tech and sometimes even older than that depending on the different levels, factors, etc.
