Even if tomorrow someone magically snapped their fingers and it came into being and millions of these units were produced the odds of finding a funded address are still so close to zero as to be zero.

If someone somehow invents it, over time he may dramatically improve it. For example, first ASIC antminer called S1 had a hashrate of 180 GH/s. Now we have Bitcoin Miner S19 XP Hyd. with a hashrate of 250000 GH/s. Its hashrate is 1388 times higher then the hashrate of S1.
Definitely, one needs tons of money to fund the research and this should be done silently, without leaking any info. In 2010 devices could rarely go higher than 1 GH/s, modern devices offer up to 250000 times more GH/s. But if we somehow invent quantum ASIC, we may hack addresses.
Okay, I know I went into science fiction, just wanted to know if its possible to create an ASIC miner for customized bitcoin address generator. My question is answered, many thanks!
