Ugh! I stopped stopping to update this page because I got the feedback that it's not a good idea! I might stop stopping to stop! So don't count on it!

I have stopped updating this page because it's too much work and I have been lazy with updating my resume and web pages lately! [Also aren't we passed the point of manually editing this stuff and AI should just take care of it without us asking? UGH!] But guess what? I have been busy with doing actual cool work instead! Checkout my twitter (or X or whatever!) for more updates!
