Well, it would have been hard to be eBPF because it pre-dated it. But perhaps you meant to say that eBPF is not DTrace? On that point, certainly agreed.
Dtrace provided huge value for quite little implementation effort. It has taken a positively enormous amount of more grueling, detailed work to make eBPF much more capable. It might not have been done without dtrace demonstrating the value available, but I credit eBPF to the people who did that hard work.
