goal: know where every idea came from — and cite it cold
objective Trace the family tree from a 1997 research paper to today's chips, and hold the honest controversy in view. History is how you sound authoritative and anticipate what comes next.
Acronyms above, spelled out: AEGIS = the name of a 1997 secure-bootstrap architecture. TCPA = Trusted Computing Platform Alliance. TPM = Trusted Platform Module (the security chip). TCG = Trusted Computing Group (the standards body).
The honest controversy (hold both sides)
Critics (Cambridge's Ross Anderson; the Free Software Foundation, which called it "treacherous computing") warned the same chip that lets you verify a machine also lets a platform owner control what software you may run.
This dual-use tension never went away — it just moved to the cloud. An expert can argue both the security case and the civil-liberties case without strawmanning either.

mastery gate 2
Redraw the timeline from memory with decade-correct dates. Name the AEGIS contribution in one sentence. Argue both sides of the controversy. Catch the trap: "TPM 1.2 (2011)" is the last revision of a line that began around 2003–2005.
