I just ran a quick test using Casey Muratori's termbench (https://github.com/cmuratori/termbench) you are an order of magnitude slower than Alacritty, and also significantly slower than iTerm. Warp also locks up pretty severely and only shows a new frame once every few seconds during most of the run.
I had a similar experience with AMD back in the day. I was probably a similar age and damaged the pins on my new Athlon XP 2500+. I called them up and they ended up sending me a 2800+ as a replacement.
The $2.6 billion price tag is not just for the rover, it includes R&D for the rover itself, employee salaries, Sky Crane & parachute R&D as well as the rocket to launch it, which cost over $100 million.
Also included in the budget is funding needed for all of the science teams to do what they do over the next few years while the rover does experiments.
