With over 6 years experience of writing firmware, it would be nice to capitalise on that, if you enjoy that kind of work. AI will upend that occupation a great deal but people will still be required to manage creation of the end product - could be good if you can ride that wave end enjoy it.
ROI for education courses is tricky to judge, in terms of both the time and the money invested. Perhaps there is a compromise to be had with a shorter course; are there any one year CS/CE style courses? Something that combined with your firmware experience would get you to the interviews.
Honestly, I'm probably operating on old views (pre-AI) of the embedded space. I do want to stick to firmware development but in today's world, I don't know what the job market will look like by the time I get that degree. But I highly doubt it would take over highly regulated industries. Who knows.
In terms of the ROI, I honestly have no sense of it either. The coursework is still operating on pre-AI curriculum. I've tried hard to cater my electives towards DSP cause there frankly are not much CE/CS course offerings in my program available to me (its actually quite rare for U.S. schools to allow students to pursue a 2nd bachelor's degree as its own separate program). In terms of coursework, I've taken the following:
- Circuits 1 (analysis of circuits with passive components)
- Intro to Digital Circuits
- Signals and Systems 1 (basic intro to LTI systems, sampling, frequency spectrum analysis, etc)
- Intro HDL and programmable logic (FPGA programming to build more complicated digital circuits)
- Electromagnetics 1
And this upcoming year, I will take
- Circuits 2 (transistors, mixed signal circuit analysis)
- Circuits 3 (amplifiers, sequential digital circuits, timing analysis, etc).
- DSP (FIR & IIR digital filter design, FFT, etc)
- DSP applications (actually mcu programming, so its most relevant)
- Computer Controlled Systems (involves mcu programming)
I figure if I finish this BSEE, it would open more opportunities to study whatever adjacent grad school programs.
