Rabois’s pushback to remote work comes at a time when many workers are pushing to continue having the option, and companies who allowed it during the pandemic are deciding what their policies will look like moving forward. According to ADP Research Institute, 64% of workers surveyed said they would consider looking for another job if their employer asked them to return full-time.

While Protocol talked to other investors who argued that asking workers to return to the office shouldn’t be a big deal, not everyone agrees, and the debate has spilled over onto Twitter, giving the public a glimpse into how executives and investors view the issue.

In a response to Rabois’s tweet about only funding IRL startups, Jeremy Stoppelmann, cofounder and CEO of Yelp, tweeted that Rabois’s tweet was the “Equivalent to ‘looking to fund startups running Windows95.’”.

Check it out and post some of the stuff from it. My favorite because of fuel prices was this:

Many innovations in the mobility sector will be on the agenda, among them Japanese electric inflatable vehicles transportable in a backpack and operational in just a few seconds from Poimo, which will be seen for the first time outside Japan.

You will find many more innovations to investigate and post. Just google the companies listed in the link and their innovations.

VivaTech is the world’s rendezvous for startups and leaders to celebrate innovation. It’s a gathering of the world’s brightest minds, talents, and products.

Circa 2006 string theory would explain everything even extradimensional beings or even weird phenomenon. Basically it could even explain something even greater about our existence that even a God level entity had a grand design of our universe. It could even explain miracles by these entities using string theory. Even Einstein thought that there could be a great designer and oddly enough this could explain all things in physics and our world even an infinite multiverse that our universe is much more odd then we previously thought. String theory could even essentially be the next step after quantum mechanics.

In the first part of this paper, we explain what empirical evidence points to the need for having an effective grand unification-like symmetry possessing the symmetry SU-color in 4D. If one assumes the premises of a future predictive theory including gravity — be it string/M-theory or a reincarnation — this evidence then suggests that such a theory should lead to an effective grand unification-like symmetry as above in 4D, near the string-GUT-scale, rather than the standard model symmetry. Advantages of an effective supersymmetric G(224) = SU L × SU R × SU c or SO(10) symmetry in 4D in explaining (i) observed neutrino oscillations, (ii) baryogenesis via leptogenesis, and (iii) certain fermion mass-relations are noted. And certain distinguishing tests of a SUSY G(224) or SO(10)-framework involving CP and flavor violations (as in μ → eγ, τ → μγ, edm’s of the neutron and the electron) as well as proton decay are briefly mentioned.

Recalling some of the successes we have had in our understanding of nature so far, and the current difficulties of string/M-theory as regards the large multiplicity of string vacua, some comments are made on the traditional goal of understanding vis a vis the recently evolved view of landscape and anthropism.

Circa 2019

According to string theory, all particles and fundamental forces arise from the vibrational states of tiny strings. For mathematical consistency, these strings vibrate in 10-dimensional spacetime. And for consistency with our familiar everyday experience of the universe, with three spatial dimensions and the dimension of time, the additional six dimensions are “compactified” so as to be undetectable.

Different compactifications lead to different solutions. In string theory, a “solution” implies a vacuum of spacetime that is governed by Einstein’s theory of gravity coupled to a quantum field theory. Each solution describes a unique universe, with its own set of particles, fundamental forces and other such defining properties.

Some string theorists have focused their efforts on trying to find ways to connect string theory to properties of our known, observable universe—particularly the standard model of particle physics, which describes all known particles and all their mutual forces except gravity.

Imagine a more sustainable future, where cellphones, smartwatches, and other wearable devices don’t have to be shelved or discarded for a newer model. Instead, they could be upgraded with the latest sensors and processors that would snap onto a device’s internal chip—like LEGO bricks incorporated into an existing build. Such reconfigurable chipware could keep devices up to date while reducing our electronic waste.

Now MIT engineers have taken a step toward that modular vision with a LEGO-like design for a stackable, reconfigurable artificial intelligence .

The design comprises alternating layers of sensing and processing elements, along with light-emitting diodes (LED) that allow for the chip’s layers to communicate optically. Other modular chip designs employ conventional wiring to relay signals between layers. Such intricate connections are difficult if not impossible to sever and rewire, making such stackable designs not reconfigurable.

Shield AI, an artificial intelligence company focusing on drones and other autonomous aircraft, is on a mission to build “the world’s best AI pilot.” To that end, the San Diego startup has raised $90 million in equity and $75 million in debt as part of a Series E fundraising round. The funding values Shield AI at $2.3 billion.

Hivemind employs state-of-the-art algorithms for planning, mapping, and state-estimation to enable drones to execute dynamic flight maneuvers. On aircraft, Hivemind enables full autonomy and is designed to run fully on the edge, disconnected from the cloud, in high-threat GPS and communication-degraded environments.

From the engine in your car to the components in your laptop, mechanical systems tend to heat up when they’re working harder. Now new research has revealed that the same can be said of the brain – and it runs hotter than was previously thought.

Some parts of the deep brain can get up to 40 °C (104 °F), a new study shows, though this varies by sex, time of day, and various other factors. Compare that with the average oral temperature in human bodies, which is typically under 37 °C (98.6 °F).

This isn’t a sign of malfunctioning though, researchers think, and may actually be evidence that the brain is operating healthily. Unusual heat signatures could potentially be used in the future to look for signs of brain damage or disorder.

Now, an international team of researchers say they have discovered a supermassive black hole that gobbles up the equivalent of one Earth every second.

By looking at other luminous objects that are billions of years old, the team confirmed the newly discovered behemoth was the brightest and fastest-growing supermassive black hole of the past 9 billion years (that we know of).

Located in the bright constellation of Centaurus, this luminous cosmic beast is more than 500 times larger than the supermassive black hole at the centre of our own galaxy.
