Heck, just being able to find an ADC with hundreds of MHz of bandwidth is kind of a big deal, let alone the computational resources now available to the modern hobbyist.
The modern day has brought incredible advancements to the modern hobbyist. Just 10 years ago, you probably still needed to play with OpAmps and Inductors to effectively read a hundreds-of-MHz signal in any real capacity (at the hobbyist scale at least: $1000 or less projects). A PC probably had the compute girth back then to interpret the data, but you still needed a high-speed, and high-quality, ADC to even read the data that quickly.
