The future is to replace the Si base with something else. Silicon Carbide has higher thermal conductivity. Bismuth-based composites provide much higher frequency.
Besides ActiveX, old (<9) Internet Explorer supported VML (Vector Markup Language), which was neither supported by anything else, nor widespread. It could be made dynamic with the help of JavaScript, and the only dynamic example I could remember was an analog clock.
"No, TPM+PIN does not help, the issue is still exploitable regardless, I asked myself this question, can it still work in a TPM+PIN environment ? Yes it does, I'm just not publishing the PoC, I think what's out there is already bad enough."
There's bigger issue than stuffing. In "rural" Hungary chain voting is customary where people are taken to the voting place by gangs and are either awarded with some money or a bag of potatoes, or threatened to be beaten if they do not comply. The first voter of the chain goes in, takes the ballot, hides it and takes it out. It is then pre-filled by the gang. The next voters take the prefilled ballot in, throw it in the box and bring a fresh clean ballot out, and so on...
In other cases, people get money/bag of potatoes for a photo of their correctly filled ballot.
