Mining equipment isn't for transaction verification. The mining
equipment is used to work on Proof-of-Work. Thanks.

Unfortunately Bitcoin does not work like those centralized systems; it
should not be surprising that a system focused so much on
decentralized and independent verification would have developers
working on so many non-bandwidth scaling solutions. These other
proposals seek to preserve existing properties of Bitcoin (such as
cheap verification, low-bandwidth) while also increasing the amount of
activity that can enjoy the decentralized fruits of Proof-of-Work
labor. But not helpful to assume this can only look like Visa or any
database on a cluster etc...

I don't suppose I could tempt you with probabilistically checkable
proofs, could I? These verify in milliseconds, grow sublinear in size
of the total data, but have no near-term proposal available yet.

Perhaps instead of failure-to-scale you mean "failure to apply
traditional scaling has already failed", which shouldn't be so
surprising given the different security model that Bitcoin operates

see the following recent text,
Bitcoin is P2P electronic cash that is valuable over legacy systems
because of the monetary autonomy it brings to its users through
decentralization. Bitcoin seeks to address the root problem with
conventional currency: all the trust that's required to make it work--
-- Not that justified trust is a bad thing, but trust makes systems
brittle, opaque, and costly to operate. Trust failures result in systemic
collapses, trust curation creates inequality and monopoly lock-in, and
naturally arising trust choke-points can be abused to deny access to
due process. Through the use of cryptographic proof and decentralized
networks Bitcoin minimizes and replaces these trust costs.
With the available technology, there are fundamental trade-offs between
scale and decentralization. If the system is too costly people will be
forced to trust third parties rather than independently enforcing the
system's rules. If the Bitcoin blockchain’s resource usage, relative
to the available technology, is too great, Bitcoin loses its competitive
advantages compared to legacy systems because validation will be too
costly (pricing out many users), forcing trust back into the system.
If capacity is too low and our methods of transacting too inefficient,
access to the chain for dispute resolution will be too costly, again
pushing trust back into the system.
