Bah!
When first deployed into a volunteer, Mr Albert Stoat, the approach showed some drawbacks viz:
1) Post operation, the subject would only speak in bursts, and then only to say "Aggleaggleaggle".
2) It turned out that during post-operative recovery a malicious person or persons unknown had installed a coin miner in Mr Stoat's firmware.
3) An MRA scan of the patient's brain later showed activity in the hypothalamus, which turned out to have somehow been overwritten with obscene MPEG shorts.
4) When the diagnostic interface was enabled and connected to a terminal, it would only play animated cat gifs.
5) Upon applying EST the patient became lucid, although only to recite a list of some four million, three hundred and ninety-two thousand, eight hundred and four userid/password pairs, after which he said "Aggleaggleaggle" and passed out.
6) Mr Stoat reacted poorly to static electricity shocks, passing out then immediately waking, saying "Aggleaggleaggle".
