I just wanted to echo @rx8pilot's sentiments about Eagle moving up.
I started using Eagle in 2014, so did not experience a lot of the trauma most old timers had to go through. However, even I noticed, less than a year after Autodesk bought Eagle in August 2016 (mid 2017?), that the updates were introducing a lot of useful features and I started to really pay attention to learn the content of each release.
The Autodesk Eagle features which were released thereafter in 2018 continued to make my life a little less painful and Eagle more easier to use (paintroller, etc.). Yet the introduction of linking Eagle to Fusion 360 was a complete game changer for me. I could now make enclosures with a lot more spatial information about the board and components at my fingertips.
That being said, it took a host of swear words for me to get up to speed on Fusion 360. As a ME novice, my only prior experience had been via SketchUp. I am still struggling with the Fusion 360 side, but I think that there is huge potential here to be explored and leveraged to improve product quality (my enclosure fits even better!) and speed up the development cycle (hand-off from EE to ME is quicker and with more information).
To nail it down further, Autodesk Fusion 360 has a ton (100?) of videos about learning the ins and outs of the product, and I tried to allocate time to go through this library even before I learned about the merge. However, all of the information seemed irrelevant to me as a beginner because I simply wanted to make an enclosure for my PCB. Yet, especially now that Eagle has been linked to Fusion 360, what is desperately needed is a handful of videos which can help us learn and leverage Fusion 360 around the topic of making an enclosure around a PCB.

https://youtu.be/oqSg1mZ-1vU?t=1980 just scratched the surface on the potential of making even your library component's have a 3D "Keep Out" space (skip to ~minute 32:00), so that you can add them to multiple projects and yet reduce the amount of work each time. I would love the information in his video, broken into 3 videos, written for the beginner (What is a Sketch? How do you manipulate Planes? Etc.).
GDPR: Also, even though GDPR can be a topic all on it's own, I realize the subject will creep into a plethora of topics over the coming years, and I wanted to give thanks for the GDPR discussion on this thread. I think all of us are still trying to wrap our heads around the regulations, and it is helpful to hear about the ramifications people are experiencing at their current jobs, especially in different parts of the world.
