Youtuber InkBox builds a complete 16-bit CPU in Excel, with 128x128, 16-color, display. No macros/VBA are used - it’s all done with formulas and conditional formatting. Well, the assembler is written in python.
Very impressive and cool!

Why not?
They now have emulators for vintage computers written in JavaScript/TypeScript which runs in a browser. Modern computers are so much faster than vintage hardware.
Until I saw “3Hz” not 3MHz or even 3KHz…
It’s so slow because it’s all done with Excel formulas - no VBA scripting. Not that VBA would be any speed demon, but would surely be a for orders of magnitude faster than formulas.
Having committed many an atrocity with massed arrays of Excel formulae I concur. Pivots, VBA, anything is faster than cell formulae.
