Perhaps adding to the growing drumbeat that Twitter (TWTR - Get Report) will ultimately be carted out of the public market in a highly-anticipated acquisition is the fact that it can't seem to hold together its own management team.

The latest departure has fueled more than Twitter M&A speculation however. Todd Morgenfeld, formerly the vice president of finance at Twitter, will join the Pinterest team, as it welcomes its first-ever CFO.

The privately held company has been valued at around $11 billion -- just a few billion dollars less than Twitter's current market cap of $16.5 billion -- and many have been wondering when they might see Pinterest as a publicly traded company.

The fact that Pinterest hasn't been acquired and has now hired a CFO has only added fuel to the IPO fire. Snapchat, another privately-held social media tech company, currently commands a market cap near $20 billion and is thought to be eyeing an IPO within the next 12 months or so.

Pinterest could be too.

Encryption has been a really hot debate in 2016, mostly fueled by the FBI vs. Apple (AAPL - Get Report) standoff earlier this year.

The issue? Tech companies have such potent protection policies and such advanced technology, that they can fully encrypt users' messages from one another.

Not only does that make it so a third party -- like hackers or the government - can't look in on certain conversations, but it's so private that not even the companies themselves can spy on users' conversations even if they wanted to. Many people are torn, with parties arguing for full privacy protection or are in favor of having the overlooking eye of "Big Brother" to solve cases and help keep us safe.

Facebook (FB - Get Report) too has found itself in hot water over its encrypted convos, particularly with its WhatsApp platform. But now the company has brought the fully encrypted service to its Facebook Messenger platform.

However, users will have to enter "Secret Conversations" to be under the end-to-end encryption blanket. This is likely because of Facebook wanting its bots to work more efficiently with users, and to avoid getting into such hot water, politically speaking.

Shares of Facebook closed at $128.47 Wednesday, up 0.2%.

Boeing (BA - Get Report) helped get the U.S. to space before and it doesn't intend to miss out on the next big frontier: Mars.

Elon Musk, the vocal CEO of Tesla Motors (TSLA - Get Report) , chairman of SolarCity (SCTY) and co-founder and CEO of SpaceX, recently announced his space-based plans and suggested that humans could be living on the red planet by the 2060s.

For what it's worth, Amazon's (AMZN - Get Report) CEO Jeff Bezos has showed a lot of interest in space travel too, with his other company Blue Origin.

But Boeing doesn't plan on watching tech titans forge the next wave of space travel. Instead, the company plans to join the race -- and perhaps even win it. As reported at Bloomberg, CEO Dennis Muilenberg envisions a future that includes a commercial space-travel market and "hypersonic aircraft shuttling travelers between continents in two hours or less. And Boeing intends to be a key player in the initial push to send humans to Mars, maybe even beating Musk to his long-time goal."

Wouldn't that be something?

Shares of Boeing closed at $134.66, up 1.9% Wednesday.
