No. Read what I said. "Innovation in mining hardware and data centers does not in any way increase bitcoin's security."

If everyone can use technology to push a higher hashrate, then what has changed? The people who can get their hands on new mining chips first have an advantage for a little while, but in the end it's a zero-sum game. The pie is 100% of hashing power/block validation power. How can you divide a pie into more than 100%?

If a dedicated data center is more effective than a commodity data center then that increases bitcoin's security, because it means a greater proportion of the hashrate resides with people who have an expensive long-term commitment to bitcoin and it's more expensive for an outsider to match that.
